NR 511 Quiz Week 2 Question 1 1 / 1 pts A 75-year-old female presents to your office complaining of dizziness and ringing in both ears for 1 day. She describes the dizziness as feeling like "the room is spinning". On physical exam, the Rinne test reveals that air conduction is greater than bone conduction bilaterally. The Weber test reveals lateralization to the left. She is unable to hear the examiner's whisper on the right side but can hear the whisper on the left side. What is the next step in helping this patient’s symptoms? Start her on high-dose Augmentin. Correct! Start the patient on a low-salt diet, prescribe meclizine for vertigo and refer her to an ENT specialist. Order a computed tomography (CT) scan to rule out acoustic neuroma. Refer the patient to the Emergency Room. Meniere's disease is characterized by vertigo, tinnitus and hearing loss. The patient self-reports vertigo and tinnitus while the results of the Weber, Rinne, and whisper test indicate sensorineural hearing loss on the right. Meniere disease is diagnosed based on history and the exclusion of other conditions as well. Referral to ENT is warranted to rule out other etiologies. The treatment for symptoms of Meniere disease is both dietary and pharmacological. Antibiotics are not indicated, nor is it necessary to send the patient to the Emergency Room. A CT scan would not help to relieve the patient's symptoms.

Question 2 1 / 1 pts A 72-year-old male patient presents to the clinic for his annual physical. He states that he is worried because he only has a bowel movement every three days. How should the clinician respond? Correct! “There is no such thing as a ‘normal’ pattern of defecation.” “You should defecate once a day.” “You should have at least three stools per week.” “You should have two to three stools per day.” There is no such thing as a “normal” pattern of defecation. Patterns of defecation vary widely and may in part be affected by dietary habits, fluid intake, bacteria in the stool, psychological stress, or voluntary

postponement of defecation. Defecating every third day could be the routine pattern for Simon. He should be questioned if this is routine for him.

Question 3 1 / 1 pts A 29-year-old female just returned from Central America with traveler’s diarrhea and presents to the clinic for evaluation. Which of the following is the best treatment? Penicillin antibiotics. Gastric lavage. Correct! Supportive care. Metronidazole (Flagyl). Enterotoxigenic Escherichia coli (ETEC) is the most common cause of traveler’s diarrhea, which occurs after ingesting contaminated food or water. It is usually self-limiting, requiring no treatment other than supportive care. It is common in developing countries. Traveler’s diarrhea caused by E coli used to be frequently treated with a 3- to 5-day course of a quinolone antibiotic, such as ciprofloxacin (Cipro).

Question 4 1 / 1 pts A 26-year-old male recently returned from a camping trip with symptoms of acute gastroenteritis. He reports that he only ate vegetables from his garden that he canned prior to his outing. Which of the following pathogens might be causing his symptoms? Clostridium perfringens. Campylobacter jejuni. Staphylococcus. Correct! Clostridium botulinum. C botulinum is an anaerobic, gram-positive bacillus that produces toxins. It is widely distributed in the soil and vegetation. Improperly processed home-canned low-acid vegetables and contaminated meats are the usual cause of food-borne botulism.

Question 5 1 / 1 pts In a young child, unilateral purulent rhinitis is most often caused by:

An allergic reaction. Correct! A foreign body. A bacterial infection. A viral infection. In a young child, unilateral purulent rhinitis is most often caused by a foreign body. The key word here is unilateral.

Question 6 1 / 1 pts A 52-year-old female is suspected of having a gastric ulcer and will undergo an Esophagogastroduodenoscopy (EGD). She is concerned because she heard that gastric ulcers can be malignant. How should the clinician respond? “Don’t worry. Gastric ulcers are not cancerous.” “You have about a 50% chance of having gastric cancer from your ulcer.” “Even if it is cancer, surgery is 100% successful.” Correct! “About 95% of gastric ulcers are benign.” About 95% of gastric ulcers are benign even though some of these seem to look malignant on x-ray.

Question 7 1 / 1 pts

An 82-year-old female has been diagnosed with irritable bowel, chronic constipation, and diverticulosis following a colonoscopy. Which pharmacological agent should the clinician recommend?

Correct! Bulking agents. Lubricants. Laxatives. Stool softeners. Bulking agents, such as psyllium preparations or methylcellulose preparations, are used for irritable bowel, chronic constipation, and diverticulosis.

Question 8 1 / 1 pts Which medications used to treat nausea and vomiting works by affecting the chemoreceptor trigger zone, thereby stimulating upper gastrointestinal motility and increasing lower esophageal sphincter pressure? Correct! Antidopaminergic and cholinergic agents, such as metoclopramide (Reglan). Tetrahydrocannabinols, such as dronabinol (Marinol). Anticholinergics, such as scopolamine (Donnatal). Antidopaminergic agents, such as prochlorperazine (Compazine). Metoclopramide (Reglan) is used for diabetic gastroparesis and postoperative nausea and vomiting. It works by affecting the chemoreceptor trigger zone, thereby stimulating upper gastrointestinal motility and increasing lower esophageal sphincter pressure.

Question 9 1 / 1 pts A 38-year-old male patient has recently had an ileostomy for ulcerative colitis. Which self-care measures should the clinician teach him about to relieve food blockage?

Lie in a supine position. Drink cold fluids. Correct! Massage the peristomal area. Take a hot shower or tub bath. Self-care measures to relieve food blockage in a client with an ileostomy include massaging the peristomal area, which may stimulate peristalsis and fecal elimination; assuming a knee-chest position to reduce intra-abdominal pressure; taking a warm shower or tub bath to relax the abdominal muscles; and drinking warm fluids or grape juice to produce a mild cathartic effect.

Question 10 1 / 1 pts A 21-year-old female patient presents to the clinic for pre-operative tonsillectomy clearance. She has heard about permanent taste changes after a tonsillectomy and is concerned. What should the clinician tell her? Correct! “You may notice a slight difference initially, but there are no lasting changes in taste.” “You will have some alterations, but we’ll have to wait and see how you are affected personally.” “Your ability to recognize sweet from salty taste will be altered for life.” “About half of the patients have some permanent alterations in the sense of taste.” Although some clients report a significant subjective drop in taste function following surgery, none have ongoing taste dysfunction.

Question 11 1 / 1 pts A 67-year old female on multiple medications for chronic conditions was just diagnosed with gastroesophageal reflux disease (GERD). In teaching the patient about the disease, what medication should the clinician recommend that the patient refrain from using? Antibiotics. Oral contraceptives.

Antifungals. Correct! Nonsteroidal anti-inflammatory drugs (NSAIDs). Clients with GERD should avoid taking NSAIDs because they tend to aggravate the already irritated gastric mucosa.

Question 12 1 / 1 pts A 30-year-old male presents to the clinic with intermittent diarrhea. He is pretty sure that the antacids taken for heartburn are the cause since the loose stools always occur within 30 minutes after taking them. How should the clinician respond? “Antacids contain sorbitol or mannitol, which are sugars that aren’t absorbed and can cause fluid to be drawn into the bowel.” Correct! “Antacids may contain magnesium, which decreases bowel transit time and may contain poorly absorbed salts that draw fluid into the bowel.” “Antacids contain fructose, which may not be totally absorbed, resulting in fluid being drawn into the bowel.” “Antacids contain caffeine, which decreases bowel transit time.” Antacids may contain magnesium, which decreases bowel transit time and may contain poorly absorbed salts that result in an osmotic draw of fluid into the bowel resulting in diarrhea.

Question 13 1 / 1 pts The antibiotic of choice for recurrent acute otitis media (AOM) and/or treatment failure in children is: Correct! Amoxicillin and potassium clavulanate (Augmentin). Amoxicillin (Amoxil). Prednisone (Deltasone).

Azithromycin (Zithromax). The antibiotic of choice for recurrent AOM or treatment failure is amoxicillin and potassium clavulanate (Augmentin).

Question 14 1 / 1 pts Nausea is difficult to discern in a young child. What question should the clinician ask to determine if a child has nausea?

“Are you eating the way you normally eat?” “Are you sick to your tummy?” “Are you nauseous?” Correct! “Are you hungry?” To elicit information concerning nausea in a young child, ask the child about hunger because a young child cannot usually differentiate between hunger and mild nausea.

Question 15 1 / 1 pts When the Weber test is performed with a tuning fork to assess hearing and there is no lateralization, the clinician should document this finding as:

Perceptive deafness. Correct! A normal finding. Conductive deafness. Nerve damage.

A Weber test assesses hearing by bone conduction. With normal hearing, sound is heard equally well in both ears, meaning there is no lateralization.
