Which part of pancreas lies near the hilum of the spleen?
- A. Head
- B. Neck
- C. Body
- D. Tail
Correct Answer: D
Rationale: Step 1: The pancreas is an elongated organ located behind the stomach.
Step 2: The tail of the pancreas is the left end of the organ and is closest to the hilum of the spleen.
Step 3: The spleen and the tail of the pancreas are adjacent to each other in the upper left quadrant of the abdomen.
Step 4: Therefore, the correct answer is D: Tail.
Summary:
- A: Head is incorrect as it is the right end of the pancreas, farther away from the spleen.
- B: Neck is incorrect as it is the narrow portion between the head and body, not near the spleen.
- C: Body is incorrect as it is the central and longest part of the pancreas, not near the spleen.
- D: Tail is correct as it is the left end of the pancreas, nearest to the hilum of the spleen.

Elderly people are more likely to develop type 2 diabetes due to the decline in production.
- A. estrogen
- B. thyroid hormone
- C. follicle-stimulating hormone
- D. insulin
Correct Answer: D
Rationale: The correct answer is D: insulin. Elderly individuals are more likely to develop type 2 diabetes due to a decrease in insulin production by the pancreas and decreased sensitivity to insulin in tissues. Insulin plays a crucial role in regulating blood sugar levels by facilitating the uptake of glucose into cells for energy production. A decline in insulin production or sensitivity can lead to elevated blood sugar levels, contributing to the development of type 2 diabetes. Estrogen (choice A), thyroid hormone (choice B), and follicle-stimulating hormone (choice C) do not directly impact insulin production or sensitivity in the context of type 2 diabetes development in elderly individuals.
The nurse has identified the nursing diagnosis of fatigue for a patient who is hypothyroid. What should the nurse do while caring for this patient?
- A. Monitor for changes in orientation, cognition, and behavior.
- B. Monitor for vital signs and cardiac rhythm response to activity.
- C. Monitor bowel movement frequency, consistency, shape, volume, and color.
- D. Assist in developing well-balanced meal plans consistent with level of energy expenditure.
Correct Answer: B
Rationale: Hypothyroid patients often experience fatigue due to a slowed metabolic rate, so it's essential to monitor vital signs and cardiac response to physical activity to assess for complications.
Mrs. A. is scheduled for a unilateral adrenalectomy. Her postoperative course is uneventful. Which discharge goal is most realistic for Mrs. A.?
- A. Being free of symptoms without medication
- B. Having greatly reduced symptoms on maintenance cortisone
- C. Being free of symptoms on daily ACTH injections
- D. Having activity restricted for life
Correct Answer: B
Rationale: Postoperatively, the goal for Cushing syndrome patients is typically symptom reduction with the help of maintenance cortisone.
Hypocalcemic tetany:
- A. is a consequence of a deficiency of calcitonin.
- B. is caused by a lack of TSH.
- C. is caused by osteoclastic activity.
- D. develops in response to a deficiency of parathyroid activity.
Correct Answer: D
Rationale: Step-by-step rationale:
1. Hypocalcemic tetany results from low blood calcium levels.
2. Parathyroid hormone (PTH) regulates calcium levels by increasing calcium release from bones and reabsorption in the kidneys.
3. A deficiency in parathyroid activity leads to decreased calcium levels, causing tetany.
4. Choice D is correct as it directly links hypocalcemic tetany to parathyroid dysfunction.
Summary:
A: Incorrect, calcitonin lowers blood calcium levels.
B: Incorrect, TSH regulates thyroid function, not calcium levels.
C: Incorrect, osteoclasts break down bone tissue but are not directly related to hypocalcemic tetany.
Which is a water soluble vitamin?
- A. D
- B. B12
- C. A
- D. K
Correct Answer: B
Rationale: The correct answer is B: B12. Vitamin B12 is water-soluble because it dissolves in water, allowing it to be easily absorbed and transported in the bloodstream. It plays a crucial role in nerve function, red blood cell production, and DNA synthesis. Vitamins D, A, and K are fat-soluble vitamins, meaning they are absorbed along with fats in the diet and are stored in the body's fat tissues. Since they are not water-soluble, they require bile for absorption and are stored in the body for longer periods. Hence, B12 is the only water-soluble vitamin among the given choices.
