Correct Answer: C

Rationale: The correct answer is C: Receive vaccines against infection. Following a splenectomy, the patient is at an increased risk of infection due to the absence of the spleen's immune function. Vaccines help boost the body's immunity against specific pathogens, reducing the risk of infections. This is crucial for preventing post-splenectomy infections. Now, let's analyze the other choices: A: Avoid showering for 1 week - There is no evidence to support that avoiding showering would prevent infection after a splenectomy. B: Sleep in a semi-fowler’s position - Positioning does not directly impact infection prevention post-splenectomy. D: Stay on antibiotics for life - Long-term antibiotic use can lead to antibiotic resistance and is not recommended unless specifically indicated for a different reason.

Correct Answer: C

Rationale: The correct answer is C: Vitamin D. In hypoparathyroidism, there is a deficiency of parathyroid hormone leading to low calcium levels. Vitamin D helps in the absorption of calcium from the intestines, thus aiding in maintaining normal calcium levels. It is often prescribed along with calcium supplements to support bone health and prevent complications. Folic acid (A) is not directly related to the treatment of hypoparathyroidism. Potassium (B) is not typically prescribed for this condition and can be harmful in high levels. Iron (D) is not directly involved in calcium metabolism and is not part of the standard treatment regimen for hypoparathyroidism.

Correct Answer: A

Rationale: The correct answer is A because playing card games with friends is a low-energy activity suitable for someone with decreased energy due to chemotherapy. This option promotes social interaction and mental stimulation, addressing the deficient diversional activity. B, bowling with a team, involves physical activity and may be too strenuous for someone with decreased energy. C, taking a long trip, requires significant energy and may not be feasible. D, eating lunch in a restaurant, does not address the need for diversional activity and is not specific to the client's energy limitations.

Correct Answer: B

Rationale: The correct answer is B: Volume overload with hemodilution. In deep partial-thickness burns, there can be fluid shifts leading to volume overload. This excess fluid in the intravascular space can dilute the blood, resulting in a decreased hematocrit (Hct). Reduced Hct indicates lower concentration of red blood cells in the blood. Other choices are incorrect because hypoalbuminemia would lead to hemoconcentration, metabolic acidosis would not directly cause a reduced Hct, and lack of erythropoietin factor would primarily affect erythropoiesis but not directly lead to decreased Hct.

Correct Answer: B

Rationale: The correct answer is B: The waiting area with the television turned off. This setting provides a quiet environment, minimizing distractions for the patient with a hearing deficit. It allows the nurse to communicate effectively by speaking clearly and facing the patient directly. Option A is incorrect because a closed door may not be enough to reduce background noise. Option C is incorrect as pain medication may affect the patient's ability to concentrate. Option D is incorrect because the occupational therapist working on leg exercises may create additional noise and distractions.
