Rationale: To calculate the volume to administer: (Desired dose / Concentration) = Volume to administer. In this case, (650 mg / 500 mg) x 5 mL = 6.5 mL. Therefore, the nurse should administer 6.5 mL of acetaminophen liquid per dose to provide the prescribed 650 mg of acetaminophen.

Correct Answer: C

Rationale: Bethanechol is a muscarinic agonist that stimulates muscarinic receptors. Activation of muscarinic receptors can lead to excessive perspiration (diaphoresis) due to increased cholinergic activity, affecting sweat glands. Dry mouth, hypertension, and fecal impaction are not typically associated with muscarinic stimulation.

Correct Answer: B

Rationale: The correct instruction for a client using a Nitroglycerin transdermal patch is to remove the patch each day, usually at bedtime, to prevent tolerance. The client should then apply a new patch the next morning. This practice helps maintain the effectiveness of the medication and prevents the body from becoming accustomed to the continuous presence of nitroglycerin.

Correct Answer: C

Correct Answer: A

Rationale: Bradycardia is a common sign of Digoxin toxicity. Digoxin can cause bradycardia due to its effects on the heart's electrical conduction system. Monitoring the client's heart rate regularly is essential to detect and manage toxicity promptly.
