Correct Answer: A

Rationale: The correct answer is A because gathering and organizing needed supplies is a crucial step before performing a complex dressing change. By ensuring all necessary supplies are readily available, the nurse can streamline the process, minimize interruptions, and promote efficiency. This step also helps maintain aseptic technique and prevent the spread of infection. Deciding on goals and outcomes (B) is important but typically done as part of the care planning process, not immediately before a dressing change. Assessing the patient's readiness (C) is also important but can be done concurrently with gathering supplies. Calling for assistance (D) may be necessary in some situations, but it is not the immediate step required just before changing the dressing.

Correct Answer: D

Rationale: The correct answer is D because a respiratory rate of 8 breaths/min indicates respiratory depression, a serious adverse effect of morphine. Morphine is a central nervous system depressant that can suppress the respiratory drive, leading to hypoventilation and potentially respiratory failure. This is a life-threatening complication that requires immediate intervention. A: Voiding of 350mL of concentrated urine is not typically associated with morphine use. B: An irregular heart rate of 82 beats/min is within a normal range and not a common adverse effect of morphine. C: Pupils constricted and equal is a common side effect of morphine due to its action on the central nervous system, not necessarily indicating an adverse effect.

Correct Answer: C

Rationale: The correct answer is C: Reassess the patient's pain level in 30 minutes. This is the priority action as it allows the nurse to evaluate the effectiveness of the acetaminophen in relieving the patient's headache. By reassessing the pain level, the nurse can determine if the medication is working or if further intervention is needed. A: Eliminating the headache from the care plan is not appropriate as the patient's comfort and pain relief should be a priority. B: Directing the nursing assistive personnel to inquire if the headache is relieved is not thorough assessment and does not provide direct evaluation of the patient's pain level. D: Revising the plan of care may be necessary based on the reassessment, but it is not the immediate priority compared to evaluating the patient's response to treatment.

Correct Answer: B

Rationale: The correct answer is B: Positioning the patient on his or her side. This is essential for a lumbar puncture as it helps to open up the spinal spaces, making it easier and safer for the procedure. Positioning the patient on their side also helps prevent complications such as nerve damage or spinal fluid leakage. A: Administering enemas until clear is unnecessary and not directly related to preparing a patient for a lumbar puncture. C: Removing all metal jewelry is important to prevent interference with imaging studies, but it is not directly related to preparing for a lumbar puncture. D: Removing the patient’s dentures is not specifically required for a lumbar puncture procedure.

Correct Answer: C

Rationale: The correct answer is C: “Are you feeling frightened? I’m here and I will help you.” This response acknowledges the resident’s feelings, offers reassurance, and provides support, focusing on the resident's emotional needs rather than the accuracy of her statements. It shows empathy and validation of her feelings, which can help calm the resident and build trust. Choice A is incorrect because it dismisses the resident's feelings and reality, which can lead to increased distress and confusion. Choice B is incorrect as it doesn't address the resident's emotional state or offer immediate support. Choice D is incorrect as it focuses on correcting the resident's perception rather than providing emotional support, which may lead to further distress.
