A nurse is assessing a client before administering atenolol. Which of the following findings should prompt the nurse to withhold the medication?
Blood pressure 160/94 mm Hg
Heart rate 46/min
Oxygen saturation 95%
Respiratory rate 18/min
The Correct Answer is B
A. Blood pressure 160/94 mm Hg — This elevated blood pressure supports the use of atenolol, a beta-blocker used to manage hypertension.
B. Heart rate 46/min — Atenolol can further decrease the heart rate. A heart rate below 50–60 bpm is typically a reason to withhold beta-blockers and notify the provider, as it may indicate bradycardia and risk for complications.
C. Oxygen saturation 95% — This is within the normal range and does not contraindicate atenolol administration.
D. Respiratory rate 18/min — This is a normal respiratory rate and is not a reason to withhold the medication.

Correct Answer is D
Explanation
A. Medications must be taken for the rest of the client's life, even if the client feels better — This is incorrect. TB treatment is not lifelong. The standard course is time-limited, usually 6 to 9 months, depending on the drug regimen and response to treatment.
B. Medications will need to be taken until the Mantoux test is negative — The Mantoux (PPD) test may remain positive for life after TB infection or vaccination and is not used to monitor treatment progress. This is inaccurate.
C. The client's family will not need to take medications to prevent infection — Close contacts may need prophylactic treatment, especially if they are at high risk (e.g., young children, immunocompromised). This statement is misleading.
D. A typical course of treatment involves 6 to 9 months of consistent medication use — This is correct. TB treatment typically lasts 6 to 9 months and requires strict adherence to prevent drug resistance and ensure cure.
Correct Answer is D
Explanation
A. Hold the medication in the mouth for 15 seconds before swallowing — This is incorrect. Inhaled glucocorticoids are meant to be inhaled into the lungs, not held in the mouth or swallowed.
B. Take the medication immediately when an attack starts — Inhaled glucocorticoids are not rescue medications. They are used for long-term control and prevention, not for acute asthma attacks.
C. Do not abruptly stop taking this medication: it must be tapered off — This applies to systemic (oral or IV) corticosteroids, not inhaled forms. Inhaled glucocorticoids have minimal systemic effects and do not require tapering.
D. Immediately rinse the mouth following the administration of the drug — This is correct. Rinsing the mouth helps prevent oral candidiasis (thrush), a common side effect of inhaled corticosteroids.
