The nurse plans a teaching session with a client but postpones the planned session based on which nursing problem?
- A. Knowledge deficit regarding impending surgery.
- B. Ineffective management of treatment regimen.
- C. Activity intolerance related to postoperative pain.
- D. Noncompliance with prescribed exercise plan.
Correct Answer: C
Rationale: Step-by-step rationale for choice C:
1. Activity intolerance is a priority nursing problem postoperatively due to pain.
2. Postoperative pain can limit the client's ability to perform activities.
3. Addressing activity intolerance is crucial for promoting recovery and preventing complications.
4. Delaying the teaching session helps the nurse focus on managing pain first.
Summary of why other choices are incorrect:
- Choice A: Knowledge deficit can be addressed after managing immediate postoperative issues.
- Choice B: Treatment regimen management is important but may not be as urgent as addressing activity intolerance related to pain.
- Choice D: Noncompliance with exercise plan can be addressed once the client's pain and activity intolerance are under control.

The patient is undergoing a necessary but painful procedure that is greatly increasing her anxiety. The nurse decides to use guided imagery to help alleviate the patients anxiety. What is a key part of this technique?
- A. Provide the patient with an external focus point such as a picture.
- B. Have the patient take slow, shallow breaths while staring at a focus point.
- C. Have the patient remember tactile sensations of a pleasant experience.
- D. Encourage the patient to consciously relax all of her muscles.
Correct Answer: C
Rationale: The correct answer is C because guided imagery involves using the patient's imagination to focus on pleasant sensory experiences. This helps distract the patient from the current situation and reduces anxiety. By remembering tactile sensations of a pleasant experience, the patient can create a calming mental image.
Choice A is incorrect because guided imagery does not require an external focus point like a picture. Choice B is incorrect because the technique does not involve staring at a focus point but rather focusing on mental images. Choice D is incorrect because while relaxation is beneficial, guided imagery specifically focuses on visualization of positive experiences to reduce anxiety.
What diagnostic procedure is required to make a definitive diagnosis of pulmonary embolism?
- A. Arterial blood gas (ABG) analysis.
- B. Chest x-ray examination.
- C. High resolution multidetector CT angiogram.
- D. Ventilation-perfusion scanning.
Correct Answer: C
Rationale: The correct answer is C: High resolution multidetector CT angiogram. This diagnostic procedure is required for a definitive diagnosis of pulmonary embolism because it provides detailed imaging of the pulmonary vasculature, allowing visualization of blood clots in the pulmonary arteries.
A: Arterial blood gas (ABG) analysis does not directly diagnose pulmonary embolism but may show signs of hypoxemia or respiratory alkalosis, which can be seen in some cases of pulmonary embolism.
B: Chest x-ray examination may show nonspecific findings such as atelectasis or pleural effusion but cannot definitively diagnose pulmonary embolism.
D: Ventilation-perfusion scanning is another imaging modality used in the diagnosis of pulmonary embolism, but it is less commonly used compared to CT angiogram due to lower sensitivity and specificity.
An ICU nurse has provided excellent care for a 6-year-old girl who had been admitted to the ICU for a head injury. The nurse was attentive not only to the needs of the patient but also went out of her way to care for the needs of the girls family. According to research, which of the following forms of recognition would the nurse value the most?
- A. A card from the girls family
- B. A plaque from the ICU physicians naming her as Nurse of the Year
- C. A letter of commendation from the hospitals administration
- D. A bouquet of flowers from her supervisor
Correct Answer: A
Rationale: Rationale: The correct answer is A: A card from the girl's family. The nurse would value this form of recognition the most because it directly reflects the impact of her care on the patient and her family. It is a personal, heartfelt gesture that acknowledges the nurse's compassion and dedication. A card from the family shows genuine appreciation and gratitude for the nurse's efforts, making it the most meaningful form of recognition.
Summary:
- Choice B: A plaque from the ICU physicians could be seen as a formal recognition but lacks the personal touch and direct impact of the nurse's care on the patient and family.
- Choice C: A letter of commendation from the hospital's administration is a professional acknowledgment but may not capture the emotional connection and impact that the nurse had on the family.
- Choice D: A bouquet of flowers from her supervisor is a nice gesture but does not necessarily reflect the specific impact of the nurse's care on the patient and family.
A nurse needs to communicate with a patients family regarding consent to treat an unconscious patient in the ICU. Which member of the group should the nurse approach first?
- A. A man she recognizes as the patients brother
- B. A teenage boy who approaches the nurse
- C. A woman who originally escorted the patient in
- D. A woman in the group whom the others look at and call over when the nurse approaches
Correct Answer: C
Rationale: The correct answer is C: A woman who originally escorted the patient in. This choice is correct because she is most likely the person responsible for the patient's care and thus likely has legal authority to make medical decisions on behalf of the patient. The other choices are incorrect because simply being recognized as the patient's brother (A), being a teenage boy who approaches the nurse (B), or being a woman whom the others look at and call over (D) does not necessarily indicate that they have the legal authority to make medical decisions for the unconscious patient.
A patient’s vital signs are pulse 87, respirations 24, BP of 128/64 mm Hg, and cardiac output is 4.7 L/min. The patient’s stroke volume is ______ mL. (Round to the nearest whole number.)
- A. 54
- B. 64
- C. 74
- D. 84
Correct Answer: A
Rationale: The stroke volume is calculated by dividing the cardiac output by the heart rate. Given the cardiac output of 4.7 L/min and a heart rate of 87 bpm, the stroke volume is 54 mL (4700 mL/87 bpm ≈ 54 mL). Therefore, choice A (54) is the correct answer. Choices B, C, and D are incorrect as they do not match the calculated stroke volume based on the provided cardiac output and heart rate.
