To assess the patient's deep tendon reflexes, the nurse should:
- A. Use a reflex hammer to test responses in the biceps, triceps, and patellar tendons.
- B. Measure the patient's temperature.
- C. Inspect the patient's gait.
- D. Check the patient's level of consciousness.
Correct Answer: A
Rationale: Deep tendon reflexes are tested using a reflex hammer to elicit responses in specific tendons. Temperature, gait, and level of consciousness are unrelated to reflex testing.

KL is a 34-year-old male admitted to the hospital (large trauma center) after suffering a traumatic brain injury (TBI) secondary to a serious motor vehicle accident. He was in excellent health prior to the accident. HT: 6'2" WT: 190 pounds (86 kg) What level of energy intake per day is the most appropriate for KL?
- A. 1,800 kcal
- B. 2,100 kcal
- C. 2,400 kcal
- D. 2,700 kcal
Correct Answer: C
Rationale: For a patient with traumatic brain injury (TBI), an energy intake of approximately 2,400 kcal/day is often appropriate to meet increased metabolic demands while avoiding overfeeding, which can exacerbate complications like hyperglycemia or respiratory issues.
Following discharge teaching, the nurse realizes that additional instruction is needed when the patient says what?
- A. It is important for me to avoid exposure to people with upper respiratory infections.
- B. When I begin to feel better
- C. I should stop taking the prednisone to prevent side effects.
- D. I plan to use vitamin supplements and a high-protein diet to help manage my condition.
Correct Answer: B
Rationale: Prednisone should not be stopped abruptly due to the risk of adrenal insufficiency
A drug is called an agonist if it ________.
- A. blocks a receptor
- B. interferes with neurotransmitter reuptake
- C. acts like the endogenous neurotransmitter by binding to its receptor
- D. blocks the voltage-gated calcium ion channel
Correct Answer: C
Rationale: The correct answer is C because an agonist mimics the action of the endogenous neurotransmitter by binding to its receptor. This leads to activation of the receptor and physiological response. Choice A is incorrect as an agonist does not block a receptor. Choice B is incorrect as it describes a reuptake inhibitor, not an agonist. Choice D is incorrect as it refers to a calcium channel blocker, not an agonist. In conclusion, an agonist activates a receptor by binding to it, unlike the other choices which describe different mechanisms of action.
