A nurse is assessing a clie”t prior to administering atenolol. Which of the following findings should prompt the nurse to withhold the medication?
Respiratory rate 18/min
Oxygen saturation 95%
Heart rate 46/min
Blood pressure 160/94 mm Hg
The Correct Answer is C
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."

Correct Answer is A
Explanation
A) Pulmonary artery:
The pulmonary artery carries deoxygenated blood from the right ventricle of the heart to the lungs for oxygenation. This is the correct starting location for blood flow from the heart to the lungs in the pulmonary circulation.
B) Left atrium:
The left atrium receives oxygenated blood from the pulmonary veins and pumps it into the left ventricle, not from the right ventricle to the lungs.
C) Left ventricle:
The left ventricle pumps oxygenated blood into the systemic circulation, not from the right ventricle to the lungs.
D) Pulmonary veins:
The pulmonary veins carry oxygenated blood from the lungs to the left atrium of the heart, not from the right ventricle to the lungs."
Correct Answer is D
Explanation
A) Apples:
Apples are not contraindicated with spironolactone use. There are no known interactions between spironolactone and apples.
B) Fish:
Fish is not contraindicated with spironolactone use. There are no known interactions between spironolactone and fish.
C) Crackers:
Crackers are not contraindicated with spironolactone use. There are no known interactions between spironolactone and crackers.
D) Bananas:
Bananas are high in potassium, and spironolactone is a potassium-sparing diuretic. Ingesting potassium-rich foods such as bananas while taking spironolactone can increase the risk of hyperkalemia. Therefore, the nurse should instruct the client to avoid consuming large amounts of potassium-rich foods like bananas to prevent adverse effects."
