1. A client prescribed Isosorbide Mononitrate for chronic stable Angina develops reflex tachycardia. Which of the following medications should the nurse expect to administer?
- A. Furosemide
- B. Captopril
- C. Ranolazine
- D. Metoprolol
Correct answer: D
Rationale: Metoprolol, a beta-adrenergic blocker, is commonly used to treat hypertension and stable angina pectoris. It is often prescribed to decrease heart rate in clients who develop tachycardia, such as in the case of reflex tachycardia induced by Isosorbide Mononitrate, making it the appropriate choice in this scenario. Furosemide (Choice A) is a loop diuretic used for conditions like heart failure and edema, not for reflex tachycardia. Captopril (Choice B) is an ACE inhibitor primarily used for hypertension and heart failure, not for reflex tachycardia. Ranolazine (Choice C) is used for chronic angina but does not specifically address reflex tachycardia.
2. A client has a new prescription for combination oral NRTIs for the treatment of HIV. Which of the following statements should the nurse include in discharge teaching?
- A. These medications work by inhibiting enzymes to prevent HIV replication.
- B. These medications work by preventing protein synthesis within the HIV cell.
- C. These medications work by weakening the cell wall of the HIV virus.
- D. These medications work by blocking HIV entry into cells.
Correct answer: A
Rationale: The correct answer is A. NRTI antiretroviral medications inhibit the enzyme reverse transcriptase, which is essential for HIV replication. By blocking this enzyme, the medications prevent the virus from replicating and spreading. This mechanism of action helps to control the progression of HIV infection in the body. Choices B, C, and D are incorrect because NRTIs do not work by preventing protein synthesis, weakening the cell wall of the virus, or blocking HIV entry into cells. These mechanisms are associated with different classes of antiretroviral medications used in HIV treatment.
3. A client is being taught by a healthcare professional about preventing Otitis Externa. Which of the following instructions should the healthcare professional include?
- A. Clean the ear with a cotton-tipped swab daily
- B. Place earplugs in the ears when sleeping at night
- C. Use a cool water irrigation solution to remove earwax
- D. Tip the head to the side to remove water from the ears after showering
Correct answer: D
Rationale: To prevent Otitis Externa, it is important to remove water from the ears after showering or swimming. This helps reduce the risk of moisture buildup in the ear canal, which can lead to infection. Cleaning the ear with a cotton-tipped swab daily can actually increase the risk of injury or infection. Placing earplugs in the ears when sleeping at night may trap moisture and promote bacterial growth. Using a cool water irrigation solution to remove earwax is not recommended as it can disrupt the natural balance of the ear canal.
4. 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.
5. A nurse is providing teaching for a male client who has Schizophrenia and is taking Risperidone. Which of the following instructions should the nurse include in the teaching?
- A. Add extra snacks to your diet to prevent weight loss.
- B. Notify the provider if you develop breast enlargement.
- C. You may begin to have mild seizures while taking this medication.
- D. This medication is likely to increase your libido.
Correct answer: B
Rationale: The correct answer is B: 'Notify the provider if you develop breast enlargement.' Gynecomastia (breast enlargement) and galactorrhea can occur due to an increase in prolactin levels while taking risperidone. The client should inform the provider if these manifestations occur. Choices A, C, and D are incorrect. Adding extra snacks to the diet to prevent weight loss is not a specific instruction related to risperidone. Seizures are not a common side effect of risperidone, so the statement about mild seizures is inaccurate. Risperidone is more likely to cause sexual side effects like erectile dysfunction rather than increasing libido, making choice D incorrect.
