1. A client is prescribed Bethanechol to treat urinary retention. Which of the following findings is a manifestation of muscarinic stimulation?
- A. Dry mouth
- B. Hypertension
- C. Excessive perspiration
- D. Fecal impaction
Correct answer: C
Rationale: Bethanechol is a muscarinic agonist, which stimulates muscarinic receptors. Activation of these receptors can lead to increased sweating (excessive perspiration) as a manifestation of muscarinic stimulation. Options A, B, and D are not typically associated with muscarinic stimulation. Dry mouth is a common side effect of anticholinergic medications, hypertension is not a common manifestation of muscarinic stimulation, and fecal impaction is not directly related to muscarinic receptor activation.
2. A healthcare professional is about to administer Propranolol to a patient. The healthcare professional takes the patient's apical pulse and documents it as 58 bpm. How should the healthcare professional proceed?
- A. Administer the medication as prescribed
- B. Administer half of the normal dose
- C. Consider the extended-release form of the medication
- D. Withhold administration of the medication and notify the healthcare provider
Correct answer: D
Rationale: When a patient's apical pulse is 58 bpm, it is below the normal range. Propranolol is a beta-blocker that can further lower the heart rate. Therefore, it is crucial to withhold the medication and notify the healthcare provider to evaluate the patient's condition. Administering Propranolol in this situation can exacerbate bradycardia, leading to serious complications. Choosing to administer the medication as prescribed (Choice A) can put the patient at risk. Administering half of the normal dose (Choice B) without healthcare provider guidance is not appropriate in this case. Considering the extended-release form of the medication (Choice C) does not address the immediate concern of bradycardia and is not the best course of action.
3. When administering Phenytoin, what should you monitor?
- A. Behavior
- B. Therapeutic blood levels
- C. For signs of Stevens-Johnson syndrome
- D. All of the above
Correct answer: D
Rationale: When administering Phenytoin, monitoring the patient's behavior is important to assess for any changes that may indicate adverse effects. Monitoring therapeutic blood levels helps ensure the medication is within the effective range and not causing toxicity. Additionally, being vigilant for signs of Stevens-Johnson syndrome, a severe skin reaction associated with Phenytoin use, is crucial for early detection and intervention. Therefore, monitoring behavior, therapeutic blood levels, and for signs of Stevens-Johnson syndrome are all essential when administering Phenytoin.
4. What is the expected pharmacological action of propranolol?
- A. Block stimulation of beta1 receptors
- B. Alter water and electrolyte transport in the large intestine
- C. Block stimulation of beta2 receptors
- D. Both A and C are correct
Correct answer: D
Rationale: Propranolol exerts its pharmacological action by blocking stimulation of both beta1 and beta2 receptors. By doing so, it leads to decreased heart rate and blood pressure. Therefore, both options A and C are correct as propranolol affects both types of beta receptors. Choice B is incorrect as propranolol does not alter water and electrolyte transport in the large intestine.
5. A client is receiving treatment with methotrexate. Which of the following supplements should the nurse instruct the client to take?
- A. Folic acid
- B. Vitamin D
- C. Calcium
- D. Iron
Correct answer: A
Rationale: The nurse should instruct the client to take folic acid when receiving treatment with methotrexate to reduce the risk of methotrexate toxicity. Methotrexate acts as a folic acid antagonist, leading to folic acid deficiency, which can be counteracted by supplementing with folic acid. Vitamin D, calcium, and iron are not specifically recommended to counteract methotrexate effects and do not play a significant role in mitigating methotrexate toxicity.
