Question 1 of 5
Which of the following situations represents the best example of passive immunity?
Correct Answer: B
Rationale: Passive immunity involves receiving pre-formed antibodies, best exemplified by an infant getting maternal antibodies via breast milk. Vaccinations trigger active immunity, infection produces personal antibodies, and antibiotics treat bacteria, not immunity. This natural transfer protects newborns, a concept nurses teach in infant care.
Question 2 of 5
The nurse finds that a newborn has a mean systolic pressure of 75 mmHg. How would this blood pressure be best described?
Correct Answer: A
Rationale: A newborn's systolic pressure of 75 mmHg is normal (range 65-95), not low or high. Nurses assess this for neonatal stability.
Question 3 of 5
Which physiological effect of immobility can lead to impaired circulation and increased risk of deep vein thrombosis?
Correct Answer: C
Rationale: Immobility reduces cardiac output by limiting muscle activity that aids venous return, leading to sluggish circulation and blood pooling, heightening deep vein thrombosis risk. This cardiovascular effect stems from less demand on the heart and poor venous flow, a serious concern in bedridden patients. Reduced breathing capacity affects oxygenation, not circulation directly, while muscle weakness and bone density loss impact strength and structure, not blood flow. Nurses monitor this to prevent clot formation, using interventions like leg exercises or compression devices, recognizing that circulation impairment is a critical link to thrombosis in prolonged stillness.
Question 4 of 5
Which intervention is important for preventing venous thromboembolism (VTE) in an immobile patient?
Correct Answer: A
Rationale: Encouraging ambulation and leg exercises prevents venous thromboembolism in immobile patients by boosting blood flow and reducing stasis, key to clot prevention. Sedatives increase immobility, cold compresses don't address circulation, and fluid limits harm hydration. Nurses implement this to counter VTE risk, using movement to enhance venous return, a critical strategy in immobile patient care.
Question 5 of 5
A nurse is caring for a client receiving oxygen therapy via a non-rebreather mask. What is an important nursing intervention for this client?
Correct Answer: A
Rationale: Ensuring the reservoir bag stays inflated (A) is critical for a non-rebreather, maintaining a high oxygen reserve (up to 95%) for inhalation. Client-preferred flow (B) lacks medical basis. Q2h SpO2 (C) may be too infrequent. Meal removal (D) disrupts therapy. Bag inflation, per respiratory care, ensures efficacy.
