Correct Answer: B

Rationale: Diazepam, a CNS depressant, can interact with Fentanyl causing severe sedation when administered concurrently. This is due to the additive central nervous system depressant effects of both medications, which can lead to excessive sedation, respiratory depression, and other serious adverse effects. Therefore, healthcare professionals need to monitor clients closely for signs of excessive sedation or respiratory depression when administering these medications together.

Correct Answer: B

Rationale: When administering transdermal Methylphenidate, the patch should be left on for 9 hours per day to ensure optimal absorption and effectiveness of the medication. This duration helps maintain a consistent level of the drug in the child's system. Incorrect options: A) Applying one patch once per day is not the correct dosing regimen for transdermal Methylphenidate. C) The patch should not be applied to the child's waistline as it is recommended to apply it to a clean, dry area. D) Using the opened tray within 6 months is not directly related to the administration of transdermal Methylphenidate.

Correct Answer: B

Rationale: Dopamine, when administered at a low dose, acts on beta1 receptors in the heart, leading to increased myocardial contractility. This positive inotropic effect results in improved cardiac output, which is beneficial for a client with severe heart failure. Dopamine does not typically cause lowered heart rate, decreased conduction through the AV node, or vasoconstriction of renal blood vessels at low doses.

Correct Answer: B

Rationale: The client's serum calcium level is below the expected reference range. In this case, the appropriate medication to anticipate administering is Calcium carbonate, an oral form of calcium used to increase serum calcium levels to the expected reference range.

Correct Answer: A

Rationale: The correct instruction for a client prescribed allopurinol is to drink 2 liters of water daily. This recommendation aims to reduce the risk of kidney stones, a potential side effect associated with allopurinol use. Adequate hydration helps prevent the formation of uric acid crystals in the kidneys, which can lead to kidney stones. Therefore, encouraging increased water intake is essential in the management of clients taking allopurinol.
