Correct Answer: B

Rationale: The correct answer is B: Iodine. Iodine is crucial for the production of thyroid hormones. A deficiency in iodine can lead to hypothyroidism. Calcium (Choice A) is important for bone health but is not directly related to thyroid function. Vitamin C (Choice C) is essential for the immune system and skin health but does not play a significant role in thyroid function. Iron (Choice D) is vital for red blood cell production and oxygen transport but is not specifically relevant to hypothyroidism.

Correct Answer: D

Rationale: The correct intervention for the nurse to include in the care plan for a client diagnosed with nephritic syndrome is to instruct the client to report any decrease in daily weight during treatment to the healthcare provider. A decrease in weight could indicate worsening of the nephritic syndrome or dehydration, making it crucial information for the healthcare provider to assess the client's condition. Option A is incorrect because discontinuing steroid therapy should be done under medical guidance rather than immediately if symptoms develop. Option B is incorrect because diuretics should not be taken without healthcare provider's guidance due to the risk of electrolyte imbalances. Option C is incorrect as increasing dietary sodium would exacerbate fluid retention, which is undesirable in nephritic syndrome.

Correct Answer: B

Rationale: The correct action for the nurse to take in this situation is to call the practitioner, report the client's symptoms, and obtain further orders. The client's symptoms, including severe abdominal pain, pallor, perspiration, thready rapid pulse, and feeling faint, are indicative of potential complications like internal bleeding, which require immediate medical evaluation. Explaining to the client that it is too early for pain medication or repositioning the client for comfort are not appropriate actions given the severity of the symptoms. Administering the injection early without consulting the practitioner can be dangerous and may worsen the client's condition.

Correct Answer: A

Rationale: Establishing rapport with the client is essential in postoperative care to create a trusting relationship, decrease embarrassment, and improve the client's comfort during assessments. Choice B is incorrect because the lithotomy position is not typically recommended post-hemorrhoidectomy. Choice C is incorrect because milking the tube inserted during surgery is not a standard practice after a hemorrhoidectomy. Choice D is incorrect as digitally dilating the rectal sphincter can cause harm and is not a part of routine post-hemorrhoidectomy care.

Correct Answer: D

Rationale: The structured review at the end of the Practical Nurse Course aims to prepare students for the practical nurse licensure examination. This exam is a crucial step for individuals to become licensed practical nurses, ensuring they meet the required standards and qualifications to practice in the field. Choices A, B, and C are incorrect as the focus of the review is specifically geared towards preparing students for the licensure examination, not for other courses, administrative processes, or duty assignments.
