Correct Answer: B

Rationale: The correct answer is to instruct the client to monitor drug levels regularly. This is crucial for phenytoin (Dilantin) to ensure that the medication levels are within the therapeutic range and to prevent toxicity. Choice A, taking the medication at bedtime, is not specifically required for phenytoin administration. Choice C, avoiding alcohol, is generally a good practice with medications but is not as critical as monitoring drug levels for phenytoin. Choice D, taking the medication at the same time every day, is important for consistency but does not address the specific monitoring needs of phenytoin.

Correct Answer: D

Rationale: Shortness of breath should be reported immediately as it may indicate a pneumothorax, a potential complication of thoracentesis. Diminished breath sounds on the affected side, pain at the procedure site, and blood-tinged sputum are common findings post-thoracentesis and do not necessarily indicate immediate complications like a pneumothorax.

Correct Answer: B

Rationale: Corrected Rationale: Monitoring the client's mood is essential when starting an antidepressant to assess for any changes or adverse effects related to the medication. Changes in mood can indicate the effectiveness of the antidepressant or potential side effects. Assessing appetite (Choice A) is important but not as crucial as monitoring mood in this context. Withdrawal symptoms (Choice C) are more relevant when discontinuing antidepressants rather than starting them. Energy level (Choice D) can be influenced by various factors and may not directly reflect the client's response to the antidepressant.

Correct Answer: C

Rationale: When a client receiving a blood transfusion reports chills and back pain, it indicates a possible transfusion reaction. The nurse's priority action is to stop the transfusion immediately. Continuing the transfusion at a slower rate (Choice A) can exacerbate the reaction. Administering an antipyretic (Choice B) may help with fever but does not address the underlying issue of a transfusion reaction. Notifying the healthcare provider (Choice D) is important but should not delay the immediate action of stopping the transfusion to ensure the client's safety.

Correct Answer: A

Rationale: The correct order of routes of administration from fastest to slowest rate of absorption is 1. Intravenous, 2. Sublingual, 3. Intramuscular, 4. Subcutaneous. Intravenous administration provides the fastest absorption as the drug is directly injected into the bloodstream. Sublingual administration allows for rapid absorption through the mucous membranes under the tongue. Intramuscular administration has a slower absorption rate as the drug is injected into the muscle tissue. Subcutaneous administration is the slowest as the drug is injected into the fatty tissue under the skin, leading to a slower absorption compared to the other routes.
