Pharmacology HESI 55 Questions 2023
1. A client with a diagnosis of generalized anxiety disorder is prescribed paroxetine. The nurse should instruct the client that this medication may have which potential side effect?
- A. Drowsiness
- B. Dry mouth
- C. Nausea
- D. Headache
Correct answer: A
Rationale: The correct answer is A: Drowsiness. Paroxetine, used for generalized anxiety disorder, can cause drowsiness. Clients should be advised not to drive or operate heavy machinery until they know how the medication affects them. Dry mouth, nausea, and headache are potential side effects of other medications but are not commonly associated with paroxetine. Drowsiness is a common side effect for paroxetine and can impact a client's ability to perform tasks that require alertness.
2. Which action should be taken to assess for analgesic tolerance in a client who is unable to communicate?
- A. Review the client's laboratory values for changes in peak and trough levels of the analgesic
- B. Prolong the interval between analgesic medication doses and monitor the client's vital signs
- C. Observe the client for the presence of pain behaviors before the next analgesic dose is due
- D. Ask family members to report behaviors suggesting that the client's pain has returned
Correct answer: C
Rationale: In clients who are unable to communicate, observing for pain behaviors is crucial in assessing analgesic tolerance. Changes in pain behaviors can indicate if the current analgesic regimen is effective or if tolerance has developed. Therefore, closely observing the client for pain behaviors before the next analgesic dose helps healthcare providers evaluate the client's response to pain management. Reviewing laboratory values may not directly reflect analgesic tolerance. Prolonging the interval between doses and monitoring vital signs may not provide direct information on analgesic tolerance. Relying solely on family members to report pain behaviors may not be as accurate or immediate as observing the client directly.
3. A client with a history of heart failure is prescribed carvedilol. The nurse should monitor the client for which adverse effect?
- A. Dizziness upon standing
- B. Weight loss
- C. Bradycardia
- D. Hypotension
Correct answer: D
Rationale: The correct answer is D: Hypotension. Carvedilol, a beta-blocker, can lead to hypotension by blocking the effects of adrenaline, which can cause blood vessels to dilate and reduce blood pressure. While dizziness upon standing is a potential adverse effect of carvedilol, it is more specifically related to orthostatic hypotension, which is a form of hypotension that occurs when a person stands up from a sitting or lying position. Weight loss and bradycardia are not typically associated with carvedilol use. Therefore, the nurse should primarily monitor for hypotension in a client taking carvedilol.
4. A client has sublingual nitroglycerine tablets prescribed to treat angina. The nurse realizes the client requires further education if the client makes which statements? (Select one that doesn't apply.)
- A. I will need to replace the nitroglycerine tablets every 3 to 5 months, not in a year.
- B. I should continue taking nitroglycerine tablets if I develop a headache.
- C. I understand nitroglycerine tablets do not cause addiction.
- D. If I feel dizzy when I take these, I should sit down or lie down until I feel better.
Correct answer: D
Rationale: The correct answer is D. Nitroglycerine sublingual tablets need to be replaced every 3 to 5 months, not every year, making statement A incorrect. While nitroglycerine can cause a headache, it is important to continue taking the prescribed nitroglycerine if the client has angina, making statement B accurate. Nitroglycerine tablets do not cause addiction, so statement C is correct. Dizziness and weakness are associated with the hypotensive effect of nitroglycerine; therefore, if the client feels dizzy when taking them, they should sit down or lie down until they feel better. Taking nitroglycerine tablets before an activity known to cause angina can help prevent angina attacks.
5. 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.
