Correct Answer: D

Rationale: The correct answer is developing interventions for grief and loss. In this scenario, the client's pain is not solely sensory but also affective due to grieving over the death of their spouse. It is essential to address the emotional component of pain by providing support and interventions for grief and loss. Referring the client for a psychiatric consult may not be necessary as grieving is a normal response to such a significant loss. Calling the physician for an increased dosage of pain medication or a sedative solely focuses on the sensory aspect of pain and does not address the underlying emotional distress.

Correct Answer: A

Rationale: The hypothalamus is responsible for regulating sleep patterns among other functions. Injury to the hypothalamus can disrupt the sleep-wake cycle, leading to excessive sleepiness or changes in sleep patterns. Choices B, C, and D are incorrect as they do not primarily control sleep regulation. The thalamus is involved in relaying sensory information, the cortex is responsible for higher brain functions, and the medulla controls vital functions such as heartbeat and breathing.

Correct Answer: A

Rationale: When caring for a client on ventilator support pending organ donation, maintaining the systolic blood pressure at 70mmHg or greater is crucial to ensure a proper blood supply to the donor organ. This goal is a priority to maintain the viability of the organ for donation. Choices B, C, and D are incorrect because they are unnecessary and not directly related to the immediate goal of organ donation. Maintaining urinary output, body temperature, or hematocrit levels are not the primary concerns in this situation.

Correct Answer: D

Rationale: The correct instruction for a client about to undergo pelvic ultrasonography is to 'Drink plenty of water.' A full bladder is required to serve as a landmark to define pelvic organs during the procedure. It is important to ensure the bladder is adequately filled. 'Urinate prior to the test' (Choice A) would not be appropriate as a full bladder is needed for better visualization. 'Have someone drive you home' (Choice B) is unnecessary as no sedation is given during the procedure, so the client can drive home on their own. 'Do not drink after midnight' (Choice C) is unrelated and not necessary for a pelvic ultrasonography examination.

Correct Answer: D

Rationale: A nasopharyngeal airway is measured from the tip of the nose to the earlobe. This measurement ensures that the airway is of the correct length to reach the nasopharynx without being too long or too short. Choices A, B, and C are incorrect as they do not provide the appropriate measurement for selecting the correct size of a nasopharyngeal airway. The distance from the corner of the mouth to the tragus of the ear (Choice A) is used to measure for an oropharyngeal airway, not a nasopharyngeal airway. Similarly, the other choices (B and C) do not correlate with the correct measurement of a nasopharyngeal airway.
