Correct Answer: B

Rationale: The correct answer is B: Altered level of consciousness. This is crucial as it can indicate various underlying health issues affecting Mr. Reyes. Assessing for this helps in detecting potential neurological, metabolic, or cardiac issues. A: Decreased carotid pulses - While important, it is not as critical as altered level of consciousness in this scenario. C: Bleeding from oral cavity - This is important to address but does not take priority over assessing Mr. Reyes' level of consciousness. D: Absence of deep tendon-reflexes - This is more specific to neurological assessments and may not be as urgent as assessing his level of consciousness.

Correct Answer: B

Rationale: The correct answer is B because conducting the interview in a quiet environment, like the waiting area with the television turned off, reduces background noise and distractions for the patient with a hearing deficit. This allows for better communication and understanding. A: Conducting the interview in the patient's room with the door closed may still have distractions or noise from outside the room. C: Conducting the interview in the patient's room before administration of pain medication does not address the issue of reducing background noise for better communication. D: Conducting the interview in the waiting room while the occupational therapist is working on leg exercises introduces additional distractions and noise, making it harder for the patient with a hearing deficit to communicate effectively.

Correct Answer: A

Rationale: The correct answer is A because the Nursing Interventions Classification (NIC) system is not designed to help medical students determine the cost of care. The NIC system focuses on standardizing and categorizing nursing interventions to improve communication, documentation, and patient care. Choice B is incorrect because it correctly identifies one of the benefits of using the NIC system - enhancing communication among nurses. Choice C is incorrect because it suggests a valid use of the NIC system for organizing orientation and explaining nursing interventions. Choice D is incorrect because it accurately states that the NIC system can improve documentation in the electronic health record, which is one of its purposes.

Correct Answer: D

Rationale: The correct answer is D, the elderly patient receiving a diuretic for fluid overload. This patient would benefit most from a capped IV catheter used intermittently because diuretics can lead to fluctuations in fluid balance that require careful monitoring and adjustment of IV fluids. By using the catheter intermittently, healthcare providers can better control the amount of fluid administered to prevent electrolyte imbalances. Option A is incorrect because a patient with pneumonia requiring fluids and antibiotics would likely benefit from a continuous IV to maintain stable levels of medications and hydration. Option B is incorrect as a patient with major blood loss would require continuous IV fluids to restore blood volume. Option C is incorrect as a dehydrated young child would also benefit from continuous IV fluids to rehydrate effectively.

Correct Answer: C

Rationale: The correct answer is C: Vitamin D. In hypoparathyroidism, there is a deficiency of parathyroid hormone leading to low calcium levels. Vitamin D helps in the absorption of calcium from the intestines, thus aiding in maintaining normal calcium levels. It is often prescribed along with calcium supplements to support bone health and prevent complications. Folic acid (A) is not directly related to the treatment of hypoparathyroidism. Potassium (B) is not typically prescribed for this condition and can be harmful in high levels. Iron (D) is not directly involved in calcium metabolism and is not part of the standard treatment regimen for hypoparathyroidism.
