Which of the following is the priority nursing intervention for a client experiencing a transfusion reaction?
- A. Stop transfusion immediately
- B. Check vital signs
- C. Notify the provider
- D. Flush the intravenous line
Correct Answer: A
Rationale: Transfusion reactions hemolytic or allergic kill fast; stopping the infusion halts antigen flood, the priority per ABCs to save life. Vitals, notifying, or flushing follow stopping's first. Nurses act swift, cutting the culprit, a non-negotiable step in this blood-borne crisis, trumping all else.

During artificial ventilation in a patient with chronic obstructive pulmonary disease, air trapping:
- A. Leads to hypotension when venous return is reduced significantly.
- B. Is likely to be present when the capnogram fails to reach a plateau in expiration.
- C. May be reduced by using a low respiratory rate.
- D. Is reduced by decreasing the ratio of inspiratory time to expiratory time.
Correct Answer: A
Rationale: Air trapping in COPD during mechanical ventilation occurs due to incomplete exhalation from airway obstruction, leading to intrinsic positive end-expiratory pressure (auto-PEEP). This increases intrathoracic pressure, compressing the vena cava and reducing venous return, which can cause hypotension a critical complication. A capnogram failing to plateau suggests prolonged exhalation, consistent with air trapping, but it's a diagnostic sign, not a consequence. A low respiratory rate allows more exhalation time, reducing air trapping, while decreasing the inspiratory-to-expiratory time ratio (e.g., shortening inspiration) similarly helps by extending exhalation. Positive end-expiratory pressure (PEEP) can exacerbate air trapping if excessive, but its effect depends on levels used. Hypotension from reduced venous return is a direct physiological result of severe air trapping, making it the most definitive statement in this context.
Oxygen radicals play a role in the development of which of the following options?
- A. Diabetic dyslipidaemia
- B. Insulin resistance
- C. Mitochondrial dysfunction
- D. B+C
Correct Answer: D
Rationale: Oxygen radicals torch cells insulin resistance via inflammation, mitochondrial dysfunction via damage. Dyslipidaemia rides along, not direct nurses see this duo, a chronic stress pair.
The single most effective intervention to reduce the risk of developing COPD and stop its progression is
- A. Increased physical activity
- B. Prompt intervention for chest infection
- C. Smoking Cessation
- D. Avoidance of indoor and outdoor pollutants
Correct Answer: C
Rationale: COPD's king fix quit smoking slashes risk and stalls damage, trumping exercise, infection zaps, or pollution dodges. It's the top toxin, 80% of cases, a chronic killer nurses chase down hard.
Which of the following interventions should be included in the nutrition care plan of the client with atherosclerosis?
- A. Limit sodium intake to 6 g per day
- B. Increase full-fat dairy products
- C. Increase saturated fats
- D. Increase daily intake of vegetables, fruits, and whole grains
Correct Answer: D
Rationale: Atherosclerosis plaque-laden arteries thrives on poor diet. Boosting vegetables, fruits, and whole grains slashes cholesterol and inflammation, slowing plaque via fiber and antioxidants, a cornerstone of cardiac nutrition. Sodium limits help hypertension, but 6 g exceeds heart-healthy goals (2.3 g). Full-fat dairy and saturated fats fuel plaque, worsening disease. Nurses push plant-based eating, aligning with evidence to reverse atherosclerosis's march, a proactive step over mere restriction in this vascular battle.
Clients with chronic illness want the health care system to provide them with which of the following?
- A. Less information
- B. Less travel time
- C. Ways to adjust to disease consequences
- D. Limited information on ways to cope with their symptoms
Correct Answer: C
Rationale: Chronic folks crave adaptation tools handling fear, sleep woes, or sex shifts not less info or travel ease. Nurses deliver this, a lifeline for illness' long tail, not just quick fixes.
