Antitussives are useful in blocking the cough reflex and preserving the energy associated with prolonged, nonproductive coughing. Antitussives are best used with

A) Respiratory rate 18/min:
A respiratory rate of 18/min is within the normal range for adults and is not a contraindication for administering atenolol. This finding does not warrant withholding the medication.

B) Oxygen saturation 95%:
An oxygen saturation of 95% is within the normal range and does not indicate any acute respiratory compromise. It is not a contraindication for administering atenolol.

C) Heart rate 46/min:
A heart rate of 46/min is below the normal range (typically 60-100 beats per minute for adults). Atenolol is a beta-blocker that primarily acts to reduce heart rate and blood pressure. Administering atenolol to a client with bradycardia (heart rate less than 60/min) can further decrease heart rate and may lead to symptomatic bradycardia or heart block. Therefore, the nurse should withhold atenolol in this case and notify the healthcare provider.

D) Blood pressure 160/94 mm Hg:
A blood pressure of 160/94 mm Hg indicates hypertension (elevated blood pressure). While atenolol is often prescribed for the management of hypertension, this blood pressure reading alone does not warrant withholding the medication. However, the client's bradycardia (heart rate 46/min)’is a more immediate concern that requires action."

A) "I should limit my fluid intake while taking this medication":
This statement is incorrect. Furosemide is a loop diuretic that increases urine production to reduce fluid overload in conditions like heart failure or edema. It is essential for clients taking furosemide to maintain adequate hydration to prevent dehydration. Therefore, the client should not limit their fluid intake while taking this medication.

B) "My blood pressure will increase while I am taking this medication":
This statement is incorrect. Furosemide is primarily used to reduce blood pressure by promoting diuresis and reducing fluid volume. Therefore, it is unlikely that blood pressure would increase while taking this medication.

C) "I should take this medication in the morning rather than at night":
This is the correct answer. Furosemide is usually taken in the morning to prevent nocturia (excessive urination at night), as it can increase urinary frequency. Taking it earlier in the day allows for better fluid balance during waking hours and reduces the need to wake up frequently during the night to urinate.

D) "I should eat a diet low in potassium while taking this medication":
This statement is incorrect. Furosemide can cause potassium depletion as a side effect, so clients may be advised to consume potassium-rich foods or supplements unless contraindicated due to other medical conditions. However, it is not necessary to eat a diet low in potassium while taking furosemide unless specifically instructed by a healthcare provider.
