3.

Eyewear

4.

Mask

Rationale After leaving the isolation room, the nurse should remove the gloves first because they are the first source of infection due to patient contact. Then, the nurse should remove eyewear by handling the earpieces to prevent the chance of transmission of infectious agents. Next, the nurse should remove the gown by allowing it to fall from the shoulders. Finally, the nurse should remove the mask. Test-Taking Tip: You have at least a 25% chance of selecting the correct response in multiple-choice items. If you are uncertain about a question, eliminate the choices that you believe are wrong and then call on your knowledge, skills, and abilities to choose from the remaining responses. p. 463

A patient has a body temperature of 35° C. What temperature does the nurse record in Fahrenheit? Record your answer using a whole number. °F

Rationale To convert Celsius to Fahrenheit, the Celsius reading first should be multiplied by 9/5, and then add 32 to the product. Applying this formula to 35° C, we get (35 × 9/5) + 32 = 95. https://eaqng.elsevier.com/#/quizPerformance/20135605

A registered nurse teaches a nursing student about precautions to be taken while pouring a sterile solution. Which statement made by the nursing student indicates a need for correction? Select all that apply. Some correct answers were not selected

'I should quickly pour the contents into the container.' 'I should pour fluids into the plastic molded sections.' 'I should verify the contents and expiration date.' 'I should remove the sterile seal and cap from the bottle in an upward motion.' 'I should make sure that a receptacle for a solution is located far away from the sterile work surface edge.'

Rationale The nurse should slowly pour the contents to prevent splashing. The nurse should make sure that the receptacle for the solution is located near or on a sterile work surface edge to prevent reaching over the sterile field. The contents should be poured into cups or plastic molded sections in sterile kits. The nurse should verify the contents and expiration date of the solution to ensure that the solution is viable. The nurse should remove the sterile seal and cap from the bottle in an upward motion to prevent contamination of the bottle lip. p. 476

Which factor is associated with a 0.5 to 1° C change in body temperature during a 24-hour period? Stress Exercise Hormonal level Circadian rhythm

Rationale Temperature is one of the most stable rhythms in humans. Circadian body temperature rhythm normally changes 0.5 to 1° C (0.9 to 1.8° F) during a 24-hour period. Physical and emotional stress increases body temperature through hormonal and neural stimulation, but these stressors are not associated with a 0.5 to 1° C change in body temperature during a 24-hour period. Prolonged strenuous exercise, such as long-distance running, temporarily raises body temperature. Hormonal variations during the menstrual cycle cause body temperature fluctuations. Women who have stopped menstruating often experience periods of hot flashes, in which skin temperature increases up to 4° C (7.2° F). p. 490

In which patient would a resting heart rate of 55 beats/minute be considered a normal finding? An obese patient An athlete A patient who is taking a diuretic A patient who weighs less than 90 lb

The conditioning of athletes, especially runners, allows a resting rate below 60 beats/minute without interrupting the normal sinus rhythm of the heart. A heart rate below 60 beats/minute is considered bradycardia. Athletes often maintain heart rates consistent with sinus bradycardia because their heart is an effective pump with a greater-than-normal stroke volume. An obese person may experience an increase in resting heart rate secondary to cardiac demand. Bradycardia is not associated with diuretics or weight less than 90 lbs. p. 499

The nurse is assessing the rectal temperature of a patient with an electronic thermometer. Which patient position would promote comfort? Sims’ position Sitting position Supine position High-Fowler’s position

Rationale While measuring rectal temperature with an electronic thermometer, patients are positioned in Sims’ position with the upper leg flexed to promote comfort. The sitting and supine positions are recommended for measuring blood pressure in patients with orthostatic hypertension, not for assessing rectal temperature. A patient with oxygen saturation (SpO 2) less than 90% should be placed in a high-Fowler’s position to improve ventilation. p. 513

Which task cannot be delegated to nursing assistive personnel? Open gloving Surgical hand asepsis https://eaqng.elsevier.com/#/quizPerformance/20135605

Applying a sterile gown Preparation of a sterile field

Rationale Nursing assistive personnel (NAP) are not authorized to prepare a sterile field. They can perform open gloving, perform surgical hand asepsis, and apply a sterile gown. p. 473

The nurse is attending to a patient who has a pressure ulcer that needs a dressing change. What actions should the nurse perform to ensure preparation of a sterile field? Select all that apply. Choose a clean, dry work surface above waist level. Remove bracelets and rings. Perform hand hygiene before handling equipment. Hold the inner edge of the flap when opening the dressing kit. Check the labels and condition of supply packaging and equipment.

Rationale A clean, dry, work surface above waist level should be used because a sterile object that is held below the waist is considered contaminated. Bracelets and rings can harbor microorganisms and hence need to be removed. Performing hand hygiene before handling equipment helps to reduce the spread of microorganisms. Checking labels and the condition of the supply gives an idea of any previous opening as an open supply may cause soiling or contamination; also, labels provide information about the date of packaging and other important information about the sterility of the product. The outer edge of the outermost flap should be held when opening the commercial kit as the outer surface is considered unsterile but helps to keep the inner kit sterile. https://eaqng.elsevier.com/#/quizPerformance/20135605

pp. 467-468

The nurse is caring for a patient who is suffering from a gastrointestinal infection. The nurse understands that any infection occurs in four stages. Arrange the stages of infection in the correct order. 1.

Incubation period

2.

Prodromal stage

3.

Illness stage

4.

Convalescence

Rationale The incubation period is the interval between the entrance of the pathogen to the body and the appearance of the first symptoms. It may vary from one day to several days. The prodromal phase is the interval between the onset of nonspecific symptoms and the appearance of specific symptoms of the infection. At this time, the pathogen multiplies inside the body, and the host is capable of spreading the infection. The illness stage is characterized by symptoms specific to the particular infection. The convalescence stage is the period of recovery from infection. The duration depends on many factors including the severity of infection and the immunity of the host. p. 446

What is the normal strength of a pulse? 1+ 2+ https://eaqng.elsevier.com/#/quizPerformance/20135605

3+ 4+

Rationale A normal strength pulse will be documented as 2+. A diminished or barely palpable pulse is documented as 1+; a strong pulse is documented as 3+; and a bounding pulse is documented as 4+. Study Tip: It may seem strange that a normal pulse strength is not at the top or the bottom of the possible ratings, but consider that there must be a way to show increased and decreased strengths within the scale, relative to normal. p. 500

The registered nurse delegated the task of palpating the pulse of a 75year-old obese patient to a licensed practical nurse (LPN). Which device used by the LPN would be appropriate to obtain more accurate readings in this patient? Apnea monitor Pulse oximeter Doppler device Vinyl pressure cuff

Rationale A Doppler device is used to palpate the pulse of an older adult who is obese because it provides more accurate readings. An apnea monitor is a device used to measure respiratory rate. A pulse oximeter is used to measure oxygen saturation and the values obtained with this device are less accurate. The vinyl pressure cuff is used to measure blood pressure. https://eaqng.elsevier.com/#/quizPerformance/20135605

A registered nurse teaches nursing students about nonspecific defense systems of the body to protect against infections. Which defense systems act as good examples to prevent infections? Select all that apply. Saliva Blinking Erythrocytes Macrophages Thrombocytes

Rationale Saliva, blinking, and macrophages are nonspecific body defense systems that help protect against infections. Saliva washes away particles containing microorganisms and reduces infection. Blinking reduces entry of particles containing pathogens, thus reducing the dose of organisms that cause infections. Macrophages engulf and destroy microorganisms that reach alveoli. Erythrocytes and thrombocytes are not associated with the body’s defense systems. p. 447

Which patient population would adapt for nonshivering thermogenesis when body metabolism decreases? Adults Infants Neonates Older adults https://eaqng.elsevier.com/#/quizPerformance/20135605

Rationale Neonates have a limited amount of vascular brown tissue present at birth. The brown tissue is metabolized for heat production, as neonates cannot shiver. This mechanism is called nonshivering thermogenesis. Adults, older adults, and infants may shiver involuntarily to compensate for temperature differences in the body. p. 488

A patient admitted to the hospital for fever, diarrhea, and vomiting receives the lab reports. The neutrophils are 20%. The patient becomes worried and asks the nurse about it. What is the probable reason for a reduced neutrophil count? Sepsis Allergy Viral infection Mild food poisoning

Rationale The patient has a reduced neutrophil count, which is seen in overwhelming bacterial infections such as sepsis. In these cases, more neutrophils are destroyed faster than they can be reproduced by the bone marrow. Allergy, viral infections, and mild food poisoning are not associated with low neutrophil counts. p. 451

A patient is diagnosed with influenza. Which type of isolation precaution is most appropriate for this patient? Droplet precautions Contact precautions Airborne precautions https://eaqng.elsevier.com/#/quizPerformance/20135605

Standard precautions

Rationale Influenza is transmitted via droplets larger than 5 microns. Pneumonia causes deep chest pain with a cough that transmits the infection. Therefore, the nurse should follow droplet precautions to prevent the infection transmission. The nurse should follow contact precautions if the infection transmits by direct patient or environmental contact. Airborne precautions are used to prevent infections that transmit through droplet nuclei smaller than 5 microns. Standard precautions are used to prevent infections that may be caused by blood, blood products, body fluids, secretions, nonintact skin, and mucous membranes. Test-Taking Tip: Key words or phrases in the question stem such as first, primary, early, or best are important. Similarly, words such as only, always, never, and all in the alternatives are frequently evidence of a wrong response. No real absolutes exist in life; however, every rule has its exceptions, so answer with care. p. 459

Which temperature indicates moderate hypothermia? 29° C (84.2° F) 30° C (86° F) 35° C (95° F) 36° C (96.8° F)

Rationale The temperature range for moderate hypothermia is 30 to 34° C (86 to 93.2° F). The temperature of severe hypothermia is less than 30°C (86° F). Therefore, a temperature of 29° C (84.2° F) indicates severe hypothermia. The temperature range of mild hypothermia is 34 to 36° C (93.2 to 96.8° F). https://eaqng.elsevier.com/#/quizPerformance/20135605

Test-Taking Tip: Identifying content and what is being asked about that content is critical to your choosing the correct response. Be alert for words in the stem of the item that are the same or similar in nature to those in one or two of the options. p. 493

A 54-year-old male patient who is being seen for an annual physical tells the nurse that he is having difficulty sustaining an erection. The nurse reviews his health history and notes no current health problems except medical treatment for depression. What should the nurse understand about this? A personal issue such as this is best addressed by a male physician during the examination. Erectile dysfunction affects most men over the age of 50. The patient needs to be screened for sexually transmitted infections (STIs). Antidepressant medication may be affecting the patient’s sexual functioning.

Rationale Many drugs can affect sexual function. Antidepressants can alter sexual functioning by blocking neurotransmitters. The decision to screen a patient should be based on health history, assessment, and sexual practices. p. 722

After assessing the blood pressure of four different patients, the primary health care provider recommends follow-up visits. For which patient would the primary health care provider recommend a recheck after 1

year?

Patient A Patient B Patient C Patient D

Rationale Patient B’s blood pressure reports show prehypertension; therefore, patient B should be recommended for a follow-up visit and a recheck in 1 year to minimize the chances https://eaqng.elsevier.com/#/quizPerformance/20135605

of hypertension. Patient A’s blood pressure reports are normal, so patient A should be recommended for recheck in 2 years. Patient C’s blood pressure reports are showing stage 1 hypertension, so patient C should be recommended for recheck within 1 month to control the severity of hypertension. Patient D’s blood pressure reports show stage 2 hypertension; therefore, patient D should be recommended for recheck within one week based on the severity of the condition. p. 505

Which condition is a result of the heat-loss mechanisms of the body becoming overwhelmed? Frost bite Heatstroke Hypothermia Heat exhaustion

Rationale Prolonged exposure to the sun or a high environmental temperature overwhelms the heat-loss mechanisms of the body. These conditions cause heatstroke, defined as a body temperature of 40° C (104° F) or more. Frostbite occurs when the body is exposed to subnormal temperatures. Ice crystals form inside the cells, and permanent circulatory and tissue damage occurs. Heat loss during prolonged exposure to cold overwhelms the ability of the body to produce heat, causing hypothermia. Heat exhaustion occurs when profuse diaphoresis results in excess water and electrolyte loss. p. 491

Lubricants Aneroid sphygmomanometer Wrist watch with second hand display

Rationale An oximeter is used to measure oxygen saturation by pulse oximetry. Lubricants are used to measure rectal temperature. An aneroid sphygmomanometer is used to measure blood pressure. A wrist watch with a second hand display is used to measure radial or apical pulse. p. 523

A patient is admitted in the hospital with a diagnosis of meningococcal pneumonia. Which is the priority nursing intervention in this condition? Isolating the patient Performing oral hygiene Providing antimicrobial therapy Keeping the patient well hydrated

Rationale Meningococcal pneumonia is an infectious droplet infection. Therefore, the patient should be isolated first to prevent the transmission of the disease. The nurse should isolate the patient before performing oral hygiene. The nurse should provide antimicrobial therapy after isolating the patient. The nurse should maintain adequate hydration to promote the patients’ health and reduce the risk of infections. Test-Taking Tip: Read the question carefully before looking at the answers: (1) Determine what the question is really asking; look for key words; (2) Read each answer https://eaqng.elsevier.com/#/quizPerformance/20135605

thoroughly and see if it completely covers the material asked by the question; (3) Narrow the choices by immediately eliminating answers you know are incorrect. p. 459

The nurse is comparing the temperature reading with the patient’s previous baseline temperature range. Which step of the nursing process is involved in this situation? Planning Evaluation Assessment Implementation

Rationale The evaluation step involves comparing a patient’s current temperature reading with the patient’s previous baseline and acceptable temperature range of his or her age group. This comparison reveals the presence of abnormalities. In the planning step, the nurse identifies the route by which the temperature reading should be taken, and the import...
