In assessing a patient, the nurse understands that what sym ptomology is an early sign of hypoxemia?
- A. Clubbing of nail beds
- B. Cyanosis
- C. Hypotension
- D. Restlessness
Correct Answer: D
Rationale: Step 1: Restlessness is an early sign of hypoxemia due to the body's response to low oxygen levels.
Step 2: Restlessness occurs as the body tries to increase oxygen intake.
Step 3: Other choices are incorrect because clubbing and cyanosis are late signs, while hypotension is not a specific early sign of hypoxemia.

Family assessment is essential in order to meet family nee ds. Which of the following must be assessed first to assist the nurse in providing family-centered care?
- A. Assessment of patient and family’s developmental stag es and needs
- B. Description of the patient’s home environment
- C. Identification of immediate family, extended family, a nd decision makers
- D. Observation and assessment of how family members fu nction with each other
Correct Answer: A
Rationale: The correct answer is A because assessing the patient and family's developmental stages and needs is crucial in understanding their current situation and determining the appropriate care plan. By assessing developmental stages, the nurse can tailor interventions to meet the family's specific needs. This assessment also helps in identifying potential challenges or areas requiring support.
Choice B is incorrect as it focuses solely on the physical environment and does not address the family's developmental stages and needs.
Choice C is incorrect as it emphasizes identifying family members without considering the importance of understanding their developmental stages and needs in providing family-centered care.
Choice D is incorrect as it concentrates on family dynamics without directly addressing the crucial aspect of assessing developmental stages and needs for effective family-centered care.
Ideally, by whom and when should an advance directive be developed?
- A. Family, if the patient is in critical condition.
- B. Patient as part of the hospital admission process.
- C. Patient before illness or impairment occurs.
- D. Patient’s healthcare surrogate.
Correct Answer: C
Rationale: Step-by-step rationale for choice C:
1. Advance directives should be made by the patient to reflect their wishes.
2. Developing it before illness ensures clarity and avoids confusion.
3. Patients may not be able to make informed decisions in critical conditions.
4. Family or surrogates may not accurately represent the patient's wishes.
Summary:
A - Family in critical condition may not know the patient's wishes.
B - Hospital admission process may be too late for clear decision-making.
D - Healthcare surrogate may not fully understand the patient's preferences.
The nurse is caring for a mechanically ventilated patient following bilateral lung transplantation. When planning the care of this patient, what is the priority nursing intervention?
- A. Thirty-degree elevation of head of bed
- B. Endotracheal suctioning as needed
- C. Frequent side to side repositioning
- D. Sequential compression stockings
Correct Answer: A
Rationale: The correct answer is A: Thirty-degree elevation of the head of the bed. This is the priority nursing intervention for a mechanically ventilated patient following bilateral lung transplantation because it helps optimize ventilation-perfusion matching, reduces the risk of aspiration, and improves oxygenation. Elevating the head of the bed also decreases the risk of ventilator-associated pneumonia.
B: Endotracheal suctioning as needed is important but not the priority intervention in this case.
C: Frequent side to side repositioning is important for preventing pressure ulcers but is not the priority for a ventilated patient post-lung transplant.
D: Sequential compression stockings are used for preventing deep vein thrombosis, which is important but not the priority in this scenario.
A PaCO 2 of 48 mm Hg is associated with what outcome?
- A. Hyperventilation
- B. Hypoventilation
- C. Increased absorption of O
- D. Increased excretion of HCO
Correct Answer: B
Rationale: The correct answer is B: Hypoventilation. A PaCO2 of 48 mm Hg indicates an elevated level of carbon dioxide in the blood, which is typically seen in hypoventilation where the lungs are not effectively removing CO2. Hypoventilation leads to respiratory acidosis. Option A is incorrect because hyperventilation would decrease PaCO2 levels. Option C is incorrect as it does not directly relate to PaCO2 levels. Option D is incorrect as increased excretion of HCO3- would not directly affect PaCO2 levels.
The nurse is caring for a critically ill patient with terminal cancer. The monitor alarms and shows ventricular tachycardia. The patient does not have a “do not resuscitate” order written on the chart. What is the appropriate nursing action?
- A. Contact the attending physician immediately to determ ine if CPR should be initiated.
- B. Contact the family immediately to determine if they waabnirtb .CcoPmR/te stot be started.
- C. Give emergency medications but withhold intubation.
- D. Initiate CPR and call a code.
Correct Answer: D
Rationale: The correct answer is D: Initiate CPR and call a code. In this scenario, the patient is critically ill with ventricular tachycardia, a life-threatening arrhythmia. Since there is no "do not resuscitate" order, the appropriate nursing action is to initiate CPR immediately to attempt to restore the patient's cardiac function and circulation. Calling a code will ensure that a team of healthcare providers can respond promptly with necessary interventions. Options A and B involve unnecessary delays in potentially life-saving interventions. Option C is incorrect as withholding intubation can compromise the patient's airway and oxygenation. Thus, option D is the most appropriate action to prioritize the patient's safety and well-being in this critical situation.
