HESI Practice Test Pharmacology
1. A client with osteoporosis is prescribed alendronate. The practical nurse (PN) should reinforce which instruction regarding the administration of this medication?
- A. Take the medication with a full glass of water before breakfast.
- B. Take the medication immediately after a meal.
- C. Lie down for 30 minutes after taking the medication.
- D. Crush the medication and mix it with food.
Correct answer: A
Rationale: The correct instruction for administering alendronate is to take the medication with a full glass of water before breakfast. This timing is crucial to ensure proper absorption in the body and reduce the risk of esophageal irritation. Taking it immediately after a meal or lying down for 30 minutes after may affect absorption and increase the risk of adverse effects. It should not be crushed or mixed with food to maintain its effectiveness.
2. The healthcare provider is evaluating the effectiveness of metaproterenol for how do you know it's been effective?
- A. Increased heart rate and blood pressure
- B. Decreased white blood cell count
- C. Decreased wheezing upon auscultation
- D. Decreased respiratory rate
Correct answer: C
Rationale: The effectiveness of metaproterenol, a bronchodilator, is assessed by a decrease in wheezing upon auscultation. Wheezing indicates airway constriction, and a reduction in wheezing signifies improved airflow and bronchodilation due to the medication's action. Therefore, choices A, B, and D are incorrect as they do not directly relate to the expected outcome of metaproterenol therapy.
3. The client is receiving vancomycin, and the nurse plans to draw blood for a peak and trough to determine... the best timing for these levels?
- A. Midway through administration of the IV dose and 30 minutes before the next
- B. Two hours after completion of the IV dose and 30 minutes before the next
- C. Two hours after completion of the IV dose and one hour before the next
- D. Immediately after completion of the IV dose and 30 minutes before
Correct answer: B
Rationale: To accurately determine peak and trough levels of vancomycin, blood should be drawn two hours after the completion of the IV dose and 30 minutes before the next dose. This timing allows for appropriate assessment of the drug levels in the body, ensuring accurate monitoring of therapeutic and toxic concentrations. Choice A is incorrect as drawing blood midway through administration does not provide an accurate peak level. Choice C is incorrect as drawing blood one hour before the next dose does not represent the trough level. Choice D is incorrect because drawing blood immediately after completion of the IV dose does not allow enough time for the drug to reach peak levels.
4. A client with a history of atrial fibrillation is prescribed verapamil. The nurse should monitor for which potential side effect?
- A. Constipation
- B. Diarrhea
- C. Headache
- D. Hypotension
Correct answer: A
Rationale: Verapamil, a calcium channel blocker, can commonly cause constipation due to its effects on smooth muscle relaxation in the gastrointestinal tract. Therefore, monitoring for constipation is important when a client is prescribed verapamil.
5. A client arrives at the emergency department experiencing diabetic ketoacidosis (DKA). The healthcare provider prescribes an insulin intravenous drip. Which type of insulin should the nurse locate for the registered nurse to mix into the intravenous fluids?
- A. Isophane
- B. Glargine
- C. Regular
- D. Detemir
Correct answer: C
Rationale: The correct insulin type for the nurse to mix into the intravenous fluids is regular insulin. In the scenario of diabetic ketoacidosis (DKA), rapid reduction of blood glucose levels is crucial. Regular insulin has a fast onset of action, making it suitable for intravenous administration to address the high blood sugar levels seen in DKA. Isophane, Glargine, and Detemir are not appropriate choices for intravenous administration in this emergency situation as they are intermediate-acting or long-acting insulins which do not provide the rapid response needed in DKA.
