A patient complains of tingling in his fingers. He has positive Trousseau's and Chvostek's signs. He says that he feels depressed. Choose the most likely serum calcium (Ca ) value for this patient:

Correct Answer: A

Rationale: The patient's symptoms of tingling in the fingers, positive Trousseau's and Chvostek's signs, and feeling depressed are suggestive of hypocalcemia, which is commonly associated with low serum calcium levels. In this case, the most likely serum calcium value would be below the normal range, which is around 8.5-10.5 mg/dl. Among the given choices, an extremely low calcium value of 5mg/dl (Choice D) would be more consistent with severe hypocalcemia presenting with tetany and other neuromuscular symptoms rather than depression and mild symptoms. On the other hand, a high calcium level of 11mg/dl (Choice A) would indicate hypercalcemia, which can lead to neuropsychiatric symptoms like depression, as seen in this patient's presentation. Therefore, Choice A (11mg/dl) is the most likely serum calcium value for

Correct Answer: B

Rationale: Children with urologic malformations are prone to latex allergies; parents should be advised to avoid latex exposure.

Correct Answer: B

Rationale: The nurse is testing the girl's cerebellar function by asking her to do the "finger-to-nose" test. The cerebellum is the part of the brain that plays a crucial role in coordinating movement, balance, and posture. In the finger-to-nose test, the child is asked to touch her own nose and then the nurse's finger repeatedly. A properly functioning cerebellum helps control and coordinate these precise movements. If there are issues with the cerebellar function, the child might have difficulty performing this task accurately, indicating a potential problem with motor coordination and balance.

Correct Answer: B

Rationale: When caring for Mr. Reyes, the nurse should assess for an altered level of consciousness as it is a crucial indicator of his overall neurological status. Changes in consciousness can signify multiple underlying issues such as neurological, metabolic, or circulatory problems. It is important for the nurse to monitor Mr. Reyes closely for any signs of confusion, disorientation, agitation, drowsiness, or changes in behavior that could indicate a decline in his neurological function. Assessing and addressing alterations in consciousness promptly is essential for providing appropriate care and preventing further complications.

Correct Answer: B

Rationale: Dark-skinned individuals have a lower risk of melanoma.
