Correct Answer: D

Rationale: The correct answer is D: Hypocalcemia. Severe diarrhea can lead to electrolyte imbalances, including low calcium levels. Decreased muscle tone and deep tendon reflexes are classic signs of hypocalcemia. Calcium is essential for proper muscle function and nerve transmission. Hypernatremia (
A) is high sodium levels, not related to decreased muscle tone. Hyperchloremia (
B) is high chloride levels, not associated with muscle tone changes. Hypokalemia (
C) is low potassium levels, which can cause muscle weakness but not specifically decreased muscle tone and deep tendon reflexes like hypocalcemia.

Correct Answer: B

Rationale: The correct answer is B: Discuss the negative feelings with the client. This is the most appropriate action as it allows the nurse to address and manage their own biases and attitudes towards the client in a professional and constructive manner. By acknowledging and discussing these feelings with the client, the nurse can work towards providing non-judgmental care and fostering a therapeutic relationship.

A: Sharing these feelings with the client is not appropriate as it can harm the nurse-client relationship and potentially lead to discrimination.
C: Developing a written interview form is not addressing the immediate issue of the nurse's negative attitude towards the client.
D: Avoiding eye contact with the client is unprofessional and does not address the underlying issue of the nurse's negative feelings.

Correct Answer: B

Rationale: The correct answer is B: 7th cranial nerve. Bell's palsy is caused by inflammation of the facial nerve (7th cranial nerve), leading to facial muscle weakness or paralysis. The 3rd cranial nerve (choice
A) controls eye movement, the 5th cranial nerve (choice
C) is responsible for facial sensation and chewing, and the 8th cranial nerve (choice
D) is related to hearing and balance. Bell's palsy specifically affects the facial muscles, making choice B the correct answer.

Correct Answer: C

Rationale: The correct answer is C. Rolling Mr. Gabatan on his abdomen, placing a pad under his head, and covering him with any material available is the appropriate action. This position helps protect his airway and prevents potential complications from a possible spinal injury. It also allows for better assessment of his condition by healthcare professionals.


Choice A is incorrect because leaving Mr. Gabatan on his back and instructing him to move can worsen any spinal injury he may have sustained.
Choice B is incorrect because raising him to a sitting position can also exacerbate his condition.
Choice D is incorrect because moving him without proper stabilization can lead to further injury.

Correct Answer: A

Rationale: The correct answer is A: Norepinephrine. Norepinephrine is the primary neurotransmitter that mediates the sympathetic response. It is released by sympathetic nerve endings and acts on adrenergic receptors in various target organs to initiate the "fight or flight" response. Prostaglandin, acetylcholine, and serotonin do not directly mediate the sympathetic response and are involved in different physiological processes.
