When administering amlodipine to a client with hypertension, what adverse effect should the nurse monitor for?
- A. Constipation
- B. Facial flushing
- C. Hypotension
- D. Jaundice
Correct Answer: C
Rationale: The correct answer is C, Hypotension. Amlodipine is a calcium channel blocker commonly used to treat hypertension. One of the main adverse effects of amlodipine is hypotension, leading to low blood pressure. The nurse should monitor the client for signs of hypotension such as dizziness, lightheadedness, or fainting. Choices A, B, and D are incorrect because constipation, facial flushing, and jaundice are not typically associated with amlodipine administration.

A nurse is preparing to administer ondansetron to a client. Which of the following therapeutic effects should the nurse expect from this medication?
- A. Decreased nausea
- B. Increased appetite
- C. Increased heart rate
- D. Relief of headache
Correct Answer: A
Rationale: The correct answer is A: Decreased nausea. Ondansetron is classified as an antiemetic medication, which means it is used to relieve nausea and vomiting by blocking serotonin in the chemoreceptor trigger zone. Therefore, the nurse administering ondansetron should expect a therapeutic effect of decreased nausea. Choice B, increased appetite, is incorrect as ondansetron does not affect appetite. Choice C, increased heart rate, is incorrect as ondansetron does not have a direct effect on heart rate. Choice D, relief of headache, is also incorrect as the primary therapeutic effect of ondansetron is to alleviate nausea and vomiting, not headaches.
A client receiving epoetin alfa therapy for anemia is being monitored for therapeutic effects. Which of the following laboratory values indicates the medication is effective?
- A. White blood cell count
- B. Hematocrit
- C. Platelet count
- D. Red blood cell count
Correct Answer: B
Rationale: The correct answer is B: Hematocrit. An increase in hematocrit levels indicates the effectiveness of epoetin alfa in treating anemia. Hematocrit reflects the percentage of red blood cells in the blood, so an increase in hematocrit signifies an improvement in the patient's red blood cell count and oxygen-carrying capacity. Choices A, C, and D are incorrect because white blood cell count, platelet count, and red blood cell count do not directly reflect the therapeutic effects of epoetin alfa in treating anemia.
A nurse is providing client education on how to administer insulin. Which of the following instructions should the nurse include?
- A. Administer the insulin into the deltoid muscle
- B. Rotate injection sites to prevent lipodystrophy
- C. Massage the site after injection
- D. Use the same site for each injection
Correct Answer: B
Rationale: The correct instruction for administering insulin is to rotate injection sites to prevent lipodystrophy, a common complication of insulin therapy. Injecting into the deltoid muscle (Choice A) is not recommended for insulin injections. Massaging the site after injection (Choice C) is not necessary and can potentially increase the risk of lipodystrophy. Using the same site for each injection (Choice D) can lead to localized tissue damage and absorption irregularities, making it an incorrect choice.
A client prescribed lisinopril for hypertension may experience which of the following side effects that the nurse should monitor for?
- A. Cough
- B. Weight gain
- C. Dry mouth
- D. Hyperglycemia
Correct Answer: A
Rationale: A persistent dry cough is a common side effect of lisinopril. Lisinopril is an ACE inhibitor that can cause a cough due to the accumulation of bradykinin. Weight gain, dry mouth, and hyperglycemia are not typically associated with lisinopril use, making them incorrect choices in this scenario.
A healthcare provider is reviewing the client's history before administering opioid pain medication. Which of the following conditions is a contraindication to opioid therapy?
- A. Asthma
- B. Renal failure
- C. Diabetes mellitus
- D. Obesity
Correct Answer: B
Rationale: Renal failure is a contraindication to opioid therapy due to the risk of drug accumulation and toxicity. Asthma, diabetes mellitus, and obesity are not contraindications to opioid therapy. Asthma is a respiratory condition that can be managed alongside opioids, diabetes mellitus and obesity do not directly contraindicate opioid therapy.
