Correct Answer: C

Rationale: Rationale for Choice C (Correct answer): - In type II DM, there is some insulin present but it is insufficient to meet the body's needs. - Without sufficient insulin, the body turns to breaking down protein and fatty acids for energy. - This leads to the formation of ketones, which can lead to diabetic ketoacidosis (DKA). - Therefore, the primary reason a type II diabetic does not usually develop DKA is due to insufficient insulin to prevent the breakdown of protein and fatty acids for metabolic needs. Summary of other choices: - Choice A is incorrect because there is some insulin available in type II DM, though it may be insufficient. - Choice B is incorrect as type II diabetics do have fat and protein reserves. - Choice D is incorrect as insufficient serum glucose concentrations do not directly relate to the development of DKA in type II DM.

Correct Answer: C

Rationale: The correct nursing diagnosis is C: Deficient fluid volume. The patient's symptoms indicate dehydration, as evidenced by tachycardia, increased thirst, decreased urine output, and increased body temperature. This points to a lack of fluid in the body. Option A, adult failure to thrive, does not address the immediate issue of fluid volume. Option B, hypothermia, is incorrect as the patient has an increased body temperature. Option D, nausea, is not a primary issue compared to the symptoms indicating dehydration. Therefore, the correct nursing diagnosis is C: Deficient fluid volume.

Correct Answer: D

Rationale: The correct answer is D because a regular diet with extra fruits and green vegetables can provide essential nutrients for overall health, potassium-sparing diuretics can help manage potassium levels in the body, and discontinuing oral magnesium salts can prevent further complications in the patient. Option A focuses on promoting a healthy diet, B addresses specific medication for potassium management, and C avoids potential interactions with magnesium salts. Therefore, all of the measures (A, B, and C) are necessary for comprehensive management of the patient's condition.

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: D

Rationale: The correct answer is D: To wash hands frequently. This is important in rhinitis prevention as it helps reduce the spread of viruses and bacteria that can trigger or exacerbate symptoms. Washing hands removes potential allergens and irritants, reducing the risk of rhinitis flare-ups. Choice A is incorrect as blowing the nose is necessary to clear mucus and alleviate symptoms. Choice B is irrelevant to rhinitis prevention. Choice C is not directly related to preventing rhinitis.
