1. What instructions should the practical nurse (PN) review with a client diagnosed with vaginal trichomoniasis who is prescribed oral metronidazole?
- A. Avoid direct sunlight exposure and use a sunscreen product with SPF100.
- B. The client's sexual partner(s) should also be treated.
- C. Avoid vinegar or commercial product douches.
- D. Eliminate dairy products from the diet during treatment.
Correct answer: B
Rationale: The correct answer is B. The practical nurse should instruct the client that their sexual partner(s) should also be treated when dealing with vaginal trichomoniasis. This is crucial to prevent reinfection as sexual intercourse is the route of spread for this infection. Choices A, C, and D are incorrect. While avoiding direct sunlight exposure and using sunscreen is important for some medications, it is not specifically related to metronidazole treatment for trichomoniasis. Avoiding vinegar or commercial douches is a general recommendation for vaginal health and not specific to this infection. Eliminating dairy products from the diet is not a typical instruction for clients prescribed metronidazole for vaginal trichomoniasis.
2. A client is prescribed an antacid for the treatment of peptic ulcer disease. What is the action of this medication that is effective in treating the client's ulcer?
- A. Decrease in the production of gastric secretions
- B. Production of an adherent barrier over the ulcer
- C. Maintenance of a gastric pH of 3.5 or above
- D. Decrease in the gastric motor activity
Correct answer: C
Rationale: The correct answer is C. Antacids work by neutralizing gastric acids and maintaining a gastric pH of 3.5 or above. This pH level is crucial to prevent the activation of pepsinogen, a precursor to pepsin, which can further damage the ulcer. Choice A is incorrect because antacids do not directly decrease the production of gastric secretions; they neutralize existing acid. Choice B is incorrect as antacids do not form a physical barrier over the ulcer but rather neutralize the acid around it. Choice D is also incorrect as antacids do not affect gastric motor activity but focus on reducing acidity in the stomach.
3. The practical nurse is assigned a client on digoxin therapy. Which finding is likely to predispose this client to developing digoxin toxicity?
- A. Hyponatremia
- B. Hypernatremia
- C. Hyperkalemia
- D. Hypokalemia
Correct answer: D
Rationale: Hypokalemia predisposes a client on digoxin to digoxin toxicity. Symptoms of digoxin toxicity include abdominal pain, anorexia, nausea, vomiting, visual disturbances, bradycardia, and atrioventricular (AV) dissociation. Therefore, assessment of serum potassium levels and prompt correction of hypokalemia are crucial interventions for clients taking digoxin.
4. The healthcare professional is caring for a patient with a new order for an oral laxative. Which is a contraindication in administering an oral laxative?
- A. Cardiac problems
- B. Abdominal pain of unknown origin
- C. Several hemorrhoids
- D. Chronic constipation
Correct answer: B
Rationale: Administering an oral laxative to a patient with abdominal pain of unknown origin is contraindicated because it could be a sign of a more serious underlying condition that needs immediate medical evaluation. Giving a laxative in such a situation without proper diagnosis could potentially worsen the patient's condition or delay appropriate treatment. Choice A (Cardiac problems) is not a contraindication for an oral laxative unless the patient has a specific cardiac condition that interacts with the laxative. Choice C (Several hemorrhoids) and Choice D (Chronic constipation) are not contraindications for administering an oral laxative.
5. Prior to administration of the initial dose of the GI agent misoprostol, which information should the nurse obtain from the client?
- A. Taking an anti-emetic medication
- B. History of glaucoma
- C. Currently pregnant
- D. Allergy to aspirin
Correct answer: C
Rationale: The correct answer is C. It is crucial for the nurse to obtain information regarding the client's pregnancy status before administering misoprostol, as this medication is contraindicated in pregnancy due to its potential to cause uterine contractions. This can lead to serious complications such as miscarriage or premature birth. Therefore, assessing whether the client is currently pregnant is essential to ensure the safe administration of misoprostol. Choices A, B, and D are not directly related to the administration of misoprostol. While knowing if the client is taking an anti-emetic medication may be relevant to prevent drug interactions, a history of glaucoma and allergy to aspirin are not primary concerns before administering misoprostol.
