A nurse is collecting data from a client prior to administering atenolol.
For which of the following findings should the nurse withhold the medication?
Heart rate 50/min.
Respiratory rate 18/min.
Oxygen saturation 95%.
Blood pressure 160/94 mm Hg.
The Correct Answer is A
The correct answer is choice A. Heart rate 50/min.
Choice A rationale:
Atenolol is a beta-blocker that can significantly lower heart rate. A heart rate of 50/min is considered bradycardia (slow heart rate), and administering atenolol could further decrease the heart rate to a dangerously low level. Therefore, the nurse should withhold the medication in this case.
Choice B rationale:
A respiratory rate of 18/min is within the normal range (12-20 breaths per minute) and does not contraindicate the use of atenolol. Therefore, this finding would not require withholding the medication.
Choice C rationale:
An oxygen saturation of 95% is within the normal range (typically 95-100%) and does not contraindicate the use of atenolol. Thus, this finding would not necessitate withholding the medication.
Choice D rationale:
While a blood pressure of 160/94 mm Hg indicates hypertension, atenolol is often prescribed to manage high blood pressure. Therefore, this finding would not require withholding the medication.

Correct Answer is A
Explanation
The correct answer is A. Captopril.
Choice A: Captopril Captopril is an angiotensin-converting enzyme (ACE) inhibitor used to treat conditions like high blood pressure and heart failure. One of the common side effects of ACE inhibitors is a persistent, non-productive cough. This cough occurs due to the accumulation of bradykinin, a potent peptide that can induce coughing.
Choice B: Metoprolol Metoprolol is a beta-blocker used to treat high blood pressure and heart failure. Common side effects include dizziness, slow or irregular heartbeat, and unusual tiredness or weakness. However, it is not typically associated with a non-productive cough.
Choice C: Furosemide Furosemide is a loop diuretic used to treat fluid retention (edema) in people with congestive heart failure, liver disease, or a kidney disorder. While it can cause side effects like diarrhea, constipation, and loss of appetite, a non-productive cough is not a typical side effect of Furosemide.
Choice D: Digoxin Digoxin is used to treat heart failure and irregular heartbeat. Common side effects include dizziness, slow or irregular heartbeat, and unusual tiredness or weakness. However, a non-productive cough is not a typical side effect of Digoxin.
Correct Answer is C
Explanation
Choice A rationale:
Providing samples for sputum cultures every 6 weeks is not a necessary instruction for a client with pulmonary tuberculosis. Sputum cultures are typically performed at specific intervals to monitor the progress of treatment and assess for bacterial resistance. This information is essential for healthcare providers but not for the client's daily care and safety.
Choice B rationale:
Consuming alcohol in moderation while taking antituberculosis medications is not recommended. Alcohol can interact with these medications and reduce their effectiveness. It is essential to advise the client to avoid alcohol completely while on tuberculosis treatment to ensure the best possible outcome.
Choice C rationale:
Wearing a mask while out or around crowds of people is a crucial precaution to prevent the spread of tuberculosis, which is highly contagious. Tuberculosis is transmitted through the air when an infected person coughs or sneezes, making mask-wearing an effective measure to protect both the client and others. This instruction promotes the safety of the client and the community.
Choice D rationale:
Placing tissue soiled with respiratory secretions in a paper bag for later disposal is not a recommended practice. Infectious material should be properly disposed of in biohazard containers or bags designed for infectious waste. This instruction does not follow the standard safety protocols for managing infectious materials and is not in the best interest of the client's health.
