Correct Answer: B

Rationale: When assessing a client for signs of impending death, the nurse should observe for Cheyne-Stokes respiration. This pattern involves rhythmic waxing and waning of respirations from very deep breathing to very shallow breathing with periods of temporary apnea. It is often associated with cardiac failure and can be a significant indicator of impending death. Elevated blood pressure and pulse rate are not typical signs of impending death; in fact, they may indicate other conditions. A decreased temperature is also not a common sign of impending death, as temperature changes can vary among individuals and may not always correlate with the dying process.

Correct Answer: C

Rationale: The correct answer is 'relaxation technique.' Biofeedback techniques are a form of relaxation technique that can help individuals quiet the mind, release tension, and counteract responses to stress. Teaching biofeedback techniques to the client aims to promote relaxation and stress management. Choice A, 'structure,' does not directly relate to teaching biofeedback techniques. Choice C, 'time management,' focuses on organizing tasks efficiently, not on relaxation techniques. Choice D, 'regular exercise,' although beneficial for overall health, is not specifically related to the teaching of biofeedback techniques for stress relief.

Correct Answer: B

Rationale: In performing a psychosocial assessment, the nurse follows a structured approach, starting with encouraging the client to describe problematic behaviors and situations. The next step is to elicit the client's thoughts about what has been described. This step helps gather more assessment data and understand how the client interprets the situation. Asking about feelings, exploring possible solutions, and understanding the client's intent in sharing the description are more complex processes that come later in the assessment. Therefore, the correct next step after describing behaviors and situations is to inquire about the client's thoughts.

Correct Answer: C

Rationale: Medication bound to protein reduces the availability of the drug to produce desired medicinal effects because only unbound drugs can effectively bind to active receptor sites. When a drug is bound to protein, it cannot bind with receptor sites, limiting its therapeutic impact. Choice A is incorrect because drug availability is reduced when it is bound to protein. Choice B is incorrect as rapid distribution to receptor sites is not possible if the drug is bound to protein and cannot bind with receptors. Choice D is incorrect as metabolism does not increase when the drug is bound to protein; the liver first needs to separate the drug from the protein before metabolism can occur.

Correct Answer: C

Rationale: The correct answer is a red, beefy tongue, which is characteristic of pernicious anemia due to the atrophy of the papillae on the tongue. This finding is known as glossitis. A red, beefy tongue is a classic sign of pernicious anemia. Choice A, weight loss of 10 pounds in 2 weeks, is non-specific and not a typical finding in pernicious anemia. Choice B, complaints of numbness and tingling in the extremities, are more indicative of peripheral neuropathy, a common symptom of vitamin B12 deficiency, which can be seen in pernicious anemia. Choice D, a hemoglobin level of 12.0 g/dL, falls within the normal range and does not specifically point towards pernicious anemia, which is characterized by low hemoglobin levels due to impaired absorption of vitamin B12.
