The nurse is explaining the action of insulin to a newly diagnosed diabetic client. During the teaching, the nurse reviews the process of insulin secretion in the body. The nurse is correct when stating that insulin is secreted from the:
- A. adenohypohysis.
- B. alpha cells of the pancreas.
- C. beta cells of the pancreas.
- D. parafollicular cells of the thyroid.
Correct Answer: C
Rationale: Rationale:
1. Insulin is a hormone produced by beta cells of the pancreas.
2. Beta cells are responsible for monitoring blood glucose levels and secreting insulin in response to high glucose levels.
3. Insulin helps regulate blood glucose by facilitating glucose uptake into cells.
4. Adenohypophysis secretes other hormones, not insulin.
5. Alpha cells of the pancreas secrete glucagon, not insulin.
6. Parafollicular cells of the thyroid secrete calcitonin, not insulin.
Summary:
Choice C is correct because insulin is indeed secreted from the beta cells of the pancreas. Choices A, B, and D are incorrect as they do not secrete insulin or are related to other hormones.

A nurse is making initial rounds on patients. Which intervention for a patient with poor wound healing should the nurse perform first?
- A. Reinforce the wound dressing as needed with 4 × 4 gauze.
- B. Perform the ordered dressing change twice daily.
- C. Observe wound appearance and edges.
- D. Document wound characteristics.
Correct Answer: C
Rationale: The correct answer is C: Observe wound appearance and edges. This is the first intervention the nurse should perform because assessing the wound's appearance and edges provides crucial information about the healing process and any signs of infection. It helps in determining the next steps in the care plan. Reinforcing the dressing (A) and performing dressing changes (B) should come after assessing the wound. Documenting wound characteristics (D) is important but should also follow the initial assessment.
In assisting a physician to perform a thoracentesis to Mr. Sy, how should the nurse postion a patient with pleural effusion of the left lung?
- A. supine with the left arm extended over the head
- B. sitting at the side of the bed with both arms resting on alocked overbed table
- C. high fowler’s with both arms resting on pillows
- D. semi-fowlers with both arms resting on pillows
Correct Answer: B
Rationale: The correct answer is B: sitting at the side of the bed with both arms resting on a locked overbed table. This position allows for better lung expansion and easier access to the thoracic cavity during the procedure. Sitting position helps in maximizing lung volume and facilitates drainage of pleural effusion. Arms resting on a locked overbed table helps the patient maintain a stable position and reduces the risk of movement during the procedure. Other choices are incorrect because supine position (A) may not allow for optimal lung expansion, high fowler's position (C) may not provide easy access to the thoracic cavity, and semi-fowlers position (D) may not facilitate efficient drainage of pleural effusion.
The nurse is instructing a premenopausal woman about breast self-examination. The nurse should tell the client to do her self-examination:
- A. at the end of her menstrual cycle
- B. on the 1st day of the menstrual cycle
- C. on the same day each month
- D. immediately after her menstrual period
Correct Answer: C
Rationale: Correct Answer: C - The nurse should tell the client to do her self-examination on the same day each month to establish a routine, making it easier to remember and detect any changes. This consistency helps in early detection of abnormalities.
Incorrect Choices:
A: Doing it at the end of the menstrual cycle may not be consistent due to varying cycle lengths.
B: Doing it on the 1st day of the menstrual cycle may not be practical and could lead to missing potential abnormalities.
D: Doing it immediately after her menstrual period may not provide a consistent schedule for self-examination.
A nurse is developing a care plan. Which intervention is most appropriate for the nursing diagnostic statement Risk for loneliness related to impaired verbal communication?
- A. Provide the patient with a writing board each shift.
- B. Obtain an interpreter for the patient as soon as possible.
- C. Assist the patient in performing swallowing exercises each shift.
- D. Ask the family to provide a sitter to remain with the patient at all times.
Correct Answer: A
Rationale: The correct answer is A: Provide the patient with a writing board each shift. This intervention addresses the impaired verbal communication by offering an alternative way for the patient to communicate. Writing board enables the patient to express thoughts and feelings, reducing the risk of loneliness. Choice B doesn't directly address the communication issue. Choice C is not relevant to the nursing diagnosis. Choice D, while promoting companionship, doesn't address the specific communication concern stated in the diagnosis.
The nurse is reviewing the medication history of a new preoperative patient who is nil by mouth (NPO). The nurse notes that the patient has been on long-term oral steroid therapy. The nurse understands that which of the following is the reason that steroids cannot be abruptly stopped?
- A. Higher steroid levels are needed during
- B. Malignant hypertension will occur.
- C. Respiratory failure will result.
- D. Malignant hyperthermia will result.
Correct Answer: A
Rationale: The correct answer is A because abruptly stopping steroids can lead to adrenal insufficiency due to suppression of the adrenal glands. This can result in a sudden drop in cortisol levels, which are essential for various physiological functions. Patients on long-term steroid therapy need a gradual taper to allow the adrenal glands to resume cortisol production. Choices B, C, and D are incorrect as they do not directly relate to the physiological effects of stopping steroids abruptly.
