Correct Answer: B

Rationale: The correct answer is B because it is important for the nurse to communicate directly with the patient, especially when the patient is alert and oriented. Speaking only to the patient's daughter may undermine the patient's autonomy and dignity. It is crucial for the nurse to establish rapport and build a therapeutic relationship with the patient. Making eye contact with the patient (choice A) is a good nonverbal communication technique. Leaning forward while talking with the patient (choice C) shows attentiveness and engagement. Nodding periodically while the patient is speaking (choice D) demonstrates active listening and encourages the patient to continue sharing. However, speaking only to the patient's daughter (choice B) is the incorrect choice as it neglects the patient's role in the conversation and may lead to potential issues in communication and patient-centered care.

Correct Answer: C

Rationale: Step-by-step rationale: 1. Statement C indicates a misunderstanding that medication can be stopped when feeling better, which is incorrect. 2. Hypertension is a chronic condition that often requires lifelong medication. 3. This demonstrates a lack of understanding regarding the necessity of long-term management. 4. Statements A, B, and D show knowledge about hypertension's effects, dietary management, and awareness, respectively. Summary: Statement C is incorrect as it suggests stopping medication, while statements A, B, and D show accurate understanding of hypertension.

Correct Answer: A

Rationale: The correct answer is A because compromised nutrition can lead to deficiencies in essential nutrients required for the production of blood cells and hemoglobin. Iron, vitamins, and minerals obtained from food are crucial for erythropoiesis and maintaining a healthy immune system. Without these nutrients, the body may struggle to produce an adequate amount of healthy red blood cells, leading to anemia and compromised immune function. Choice B is incorrect because excessive fat in the diet is not directly linked to interfering with the production of blood cells and hemoglobin. Choice C is incorrect as inconsistent dieting may affect overall health but is not specifically related to hematopoiesis. Choice D is incorrect because while iron and protein are important for blood cell production, excessive amounts of these elements are unlikely to interfere with the production of blood cells and hemoglobin.

Correct Answer: C

Rationale: The correct answer is C: IgM. During an acute infection, the body's initial response is rapid and non-specific, leading to the production of IgM antibodies first. IgM is the first immunoglobulin class produced in response to a new antigen, providing immediate protection. IgG is produced later in the immune response and is responsible for long-term immunity. IgE is involved in allergic reactions and parasitic infections, not typically the first response to infection. IgD is primarily found on the surface of B cells and its function is not well understood in the context of acute infections.

Correct Answer: C

Rationale: The correct answer is C: Assess apical heart before administering digitalis. This is important because digitalis can slow down the heart rate, so it is crucial to monitor the client's heart rate before giving the medication to prevent further decrease in cardiac output. Encouraging activities that engage the Valsalva maneuver (A) is contraindicated in clients with congestive heart failure as it can lead to increased intra-thoracic pressure and decreased venous return, worsening cardiac output. Encouraging the client to perform exercises (B) may also increase cardiac workload and exacerbate symptoms. Offering small frequent feedings (D) is generally beneficial for clients with congestive heart failure to prevent overeating and promote easier digestion, but it does not directly address the decreased cardiac output concern in this scenario.
