HESI Practice Test Pharmacology
1. A client diagnosed with multiple sclerosis self-administers beta-1 interferon subcutaneously
- A. Explain to the client that the medication dose may need to be increased
- B. Instruct the client to withhold the drug until the next exacerbation
- C. Advise the client to consult the healthcare provider as soon as possible
- D. Encourage the client to continue taking the medication
Correct answer: D
Rationale: Encouraging the client to continue taking the medication is crucial in the management of multiple sclerosis. Beta-1 interferon is a disease-modifying drug used to reduce the frequency and severity of relapses in multiple sclerosis. Discontinuing the medication without medical advice can lead to disease exacerbation. It is essential for the client to maintain regular dosing to achieve optimal therapeutic effects and disease control.
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. A client is prescribed verapamil for hypertension. The nurse should monitor the client for which common adverse effect?
- A. Constipation
- B. Headache
- C. Muscle cramping
- D. Fatigue
Correct answer: A
Rationale: Verapamil, a calcium channel blocker commonly used for hypertension, is known to cause constipation as a frequent adverse effect. This occurs due to its effects on smooth muscle relaxation in the gastrointestinal tract, leading to decreased motility. Headache, muscle cramping, and fatigue are not typically associated with verapamil use and are less common side effects. Therefore, the nurse should closely monitor the client for symptoms of constipation when administering verapamil.
4. What instructions should the PN reinforce with the client regarding the newly prescribed medications isosorbide dinitrate and hydrochlorothiazide?
- A. Instruct the client to use a soft bristle toothbrush.
- B. Instruct the client to slowly rise from a sitting or lying down position.
- C. Instruct the client to elevate their legs above the level of their heart.
- D. Instruct the client to limit the amount of fiber in their diet.
Correct answer: B
Rationale: The correct instruction for the client is to slowly rise from a sitting or lying down position. Isosorbide dinitrate, a nitrate, and hydrochlorothiazide, a diuretic, can both cause hypotension. When used together, their additive effects can further lower blood pressure, leading to orthostatic hypotension. Instructing the client to change positions slowly helps prevent a sudden drop in blood pressure, reducing the risk of dizziness or falls. Choices A, C, and D are incorrect because they do not directly address the potential side effect of hypotension associated with the prescribed medications. Using a soft bristle toothbrush, elevating legs above the heart level, or limiting fiber intake are not specific instructions to mitigate the risk of orthostatic hypotension.
5. A male client receives a scopolamine transdermal patch 2 hours before surgery. Four hours after surgery, the client tells the nurse that he is experiencing pain and asks why the patch is not working. Which action should the nurse take?
- A. Advise the client that the effects of the medication have worn off
- B. Explain that the medication is not given to relieve pain
- C. Check for the correct placement of the patch on the client
- D. Offer to apply a new transdermal patch to address the pain
Correct answer: B
Rationale: The correct answer is B. Scopolamine is not a pain medication; it is commonly used to prevent nausea and vomiting, particularly in surgical settings. It works on the central nervous system to help control these symptoms, not to relieve pain. Therefore, it is important for the nurse to explain to the client that the medication is not intended to relieve pain but rather to manage other specific symptoms. Checking the correct placement of the patch is also important to ensure proper administration, but addressing the misconception about the medication's purpose is the priority in this scenario. Offering to apply a new patch would not address the client's pain as scopolamine is not meant for pain relief. Advising the client that the effects have worn off is inaccurate because the medication is not used for pain management.
