Correct Answer: C

Rationale: The correct answer is C. Washing feet in hot water is not part of diabetic foot care as it can lead to burns or skin damage. A: Properly fitting shoes help prevent injuries. B: Trimming toenails straight reduces risk of ingrown nails. D: Wearing shoes on hot surfaces protects feet from burns or injuries. Overall, C is incorrect due to its potential harm to the client's feet.

Correct Answer: A

Rationale: The correct answer is A: Inspecting for bleeding or cyanosis. During uterosigmoidostomy, the nurse's critical task is to monitor for any signs of bleeding or cyanosis, which are indicators of potential complications such as hemorrhage or impaired blood flow. This involves observing the surgical site for any abnormal bleeding and assessing the skin color for signs of inadequate oxygenation. Inspecting for symptoms of peritonitis (B) is not directly related to this surgical procedure. Assessing the client's allergy to iodine (C) is important but not a critical task during the procedure. Checking for signs of electrolyte losses (D) is important but not as critical as monitoring for immediate postoperative complications like bleeding or cyanosis.

Correct Answer: C

Rationale: The correct answer is C (280 to 295mOsm/kg) because serum osmolality is primarily determined by sodium, glucose, and blood urea nitrogen levels. Normal serum sodium range is 135-145 mEq/L, which corresponds to an osmolality range of 280-295 mOsm/kg. Choices A and B are incorrect as they do not align with normal serum sodium levels. Choice D is incorrect as it includes an excessively wide range that is not consistent with normal osmolality values.

Correct Answer: D

Rationale: Correct Answer: D - Lubricating eye drops Rationale: Lubricating eye drops help prevent complications such as corneal abrasions in patients with Bell's Palsy by keeping the eye moist and preventing dryness. Bell's Palsy can cause difficulty in closing the eye properly, leading to dryness and potential damage to the cornea. Using lubricating eye drops helps maintain eye health. Summary of Incorrect Choices: A: Megavitamin therapy - Not directly related to preventing complications in Bell's Palsy. B: Application of ice to the affected area - Ice may not address eye dryness or prevent corneal abrasions. C: Elastic bandages - Not relevant to preventing complications associated with Bell's Palsy.

Correct Answer: D

Rationale: The correct answer is D: Malnutrition. Malnutrition weakens the immune system, making individuals more susceptible to contracting tuberculosis. A well-nourished individual has a stronger immune response to fight off TB bacteria. Exposure to toxic gases (A), congenital abnormalities (B), and obstruction by tumor (C) do not directly predispose a client to TB. Malnutrition is the key factor as it impairs the immune system's ability to combat the TB bacteria effectively.
