Correct Answer: A

Rationale: Collapsing the device when it is 1/2 to 2/3 full of air is the correct nursing action to ensure proper operation of a closed wound suction device (hemovac). This action maintains negative pressure, which is essential for proper suction and drainage of the wound. Emptying the device every 4 hours (Choice B) is not necessary as the focus should be on collapsing it appropriately. Replacing the device every 24 hours (Choice C) is not a standard practice unless indicated by the healthcare provider. Keeping the device above the level of the surgical site (Choice D) is not necessary for the device's proper operation; collapsing it to maintain negative pressure is the key action.

Correct Answer: D

Rationale: The correct answer is D: Tardive dyskinesia. Tardive dyskinesia is a potential side effect of long-term antipsychotic use, characterized by involuntary movements like lip smacking and repetitive, purposeless movements. Choice A, dystonia, presents with sustained or repetitive muscle contractions. Choice B, akathisia, involves motor restlessness and a compelling need to be in constant motion. Choice C, bradykinesia, refers to slowness of movement typically seen in Parkinson's disease, not lip smacking and teeth grinding, which are indicative of tardive dyskinesia.

Correct Answer: A

Rationale: The correct answer is A. Asking the client what can be done to help overcome the fear of self-injections demonstrates empathy, understanding, and a willingness to support the client in addressing their barriers. This approach facilitates open communication, acknowledges the client's feelings, and involves them in the decision-making process. Choices B and C are authoritarian and may increase resistance in the client by being directive and not considering the client's perspective. Choice D, while positive, does not directly address the client's fear and resistance to self-injections, missing the opportunity to explore the underlying issues.

Correct Answer: A

Rationale: The correct answer is A. Stopping antihypertensive medication abruptly can lead to rebound hypertension, which can be dangerous. Clients should never discontinue their medication without consulting their healthcare provider first. Choice B is correct because monitoring blood pressure is essential when taking antihypertensive medication to ensure it stays within the target range. Choice C is correct as alcohol can potentiate the hypotensive effects of antihypertensive medications. Choice D is correct as orthostatic hypotension can occur, so rising slowly helps prevent dizziness and falls. Therefore, choice A is the statement that indicates a need for further teaching.

Correct Answer: C

Rationale: The correct answer is C: Rash, blood dyscrasias, and severe depression are serious side effects of haloperidol that necessitate withholding the dose and prompt further evaluation. Rash can indicate an allergic reaction, blood dyscrasias are serious blood disorders that can be life-threatening, and severe depression may worsen with haloperidol use. Choices A, B, and D are incorrect because drowsiness, lethargy, inactivity, dry mouth, nasal congestion, blurred vision, hyperglycemia, weight gain, and edema are common side effects of haloperidol that may not necessarily contraindicate its use but should be monitored and managed appropriately.
