Correct Answer: B

Rationale: Rationale: 1. NPH insulin peaks in 4-12 hours, making 4:00 PM the highest risk time. 2. 10:00 AM is too soon for peak effect. 3. Noon is too early for peak effect. 4. 10:00 PM is too late for peak effect. In summary, B is correct as it aligns with NPH insulin peak time, while other options are too early or too late.

Correct Answer: A

Rationale: The correct answer is A: Hyperkalemia. In acute Addisonian crisis, the adrenal glands do not produce enough cortisol and aldosterone, leading to electrolyte imbalances. This results in increased potassium levels (hyperkalemia) due to lack of aldosterone to promote potassium excretion. Hypernatremia (choice B) is less likely as aldosterone deficiency leads to sodium loss. Reduced BUN (choice C) is unlikely as Addison's crisis does not directly affect urea levels. Hyperglycemia (choice D) is not typically seen in Addisonian crisis as cortisol deficiency usually results in hypoglycemia.

Correct Answer: C

Rationale: The correct answer is C because it focuses on the client actively engaging in reducing tension, which is essential in managing anxiety. This outcome is measurable and client-centered. A: Verbalizing feelings is important, but it does not necessarily lead to reduction in anxiety. B: Not guessing prognosis is helpful, but it does not address the active management of anxiety. D: Stopping seeking information may not be beneficial as knowledge can empower the client in coping with the diagnosis.

Correct Answer: C

Rationale: Correct Answer: C - Dryness of mouth Rationale: 1. Trihexyphenidyl is an anticholinergic medication commonly used to treat Parkinson's disease. 2. Anticholinergic drugs inhibit the parasympathetic nervous system, leading to decreased secretions. 3. Dryness of mouth (xerostomia) is a common side effect of anticholinergic medications. 4. Excessive salivation, bradycardia, and constipation are not typically associated with anticholinergic drugs, making them incorrect choices.

Correct Answer: C

Rationale: The correct answer is C: Pernicious anemia. Vitamin B12 is essential for the production of red blood cells, and its deficiency can lead to pernicious anemia, characterized by decreased red blood cell production. Without adequate vitamin B12, the body cannot properly utilize iron, leading to anemia. Iron deficiency anemia (choice A) is a result of insufficient iron levels, not vitamin B12 deficiency. Sickle cell anemia (choice B) is a genetic disorder affecting hemoglobin, not related to vitamin B12 deficiency. Acquired haemolytic anemia (choice D) is caused by the premature destruction of red blood cells, not by vitamin B12 deficiency.
