Correct Answer: A

Rationale: The correct answer is A: Monitor aPTT levels. This is crucial in intravenous heparin therapy to ensure the therapeutic range is maintained for anticoagulation without causing bleeding. Monitoring aPTT helps adjust heparin dosage to prevent clot formation or excessive bleeding. B: Monitoring for bleeding is important but not the most important action compared to monitoring aPTT levels for appropriate dosing. C: Checking platelet count is important for some anticoagulants like heparin, but aPTT monitoring is more directly related to heparin's anticoagulant effect. D: Administering a heparin antidote (protamine sulfate) is necessary in case of heparin overdose or in emergency situations but is not the primary action in routine care.

Correct Answer: B

Rationale: The given ABG values fall within normal ranges, indicating homeostasis. The pH is within the normal range (7.35-7.45), indicating acid-base balance. The PO2 is slightly lower but still within the normal range (80-100 mmHg). PCO2 falls within the normal range (35-45 mmHg), showing effective ventilation. The HCO3 level is also within the normal range (22-26 mEq/L), indicating proper kidney function. Therefore, all values are within normal limits, reflecting a state of homeostasis. Other choices are incorrect as they suggest imbalances in acid-base status, which is not seen with these values.

Correct Answer: A

Rationale: The correct answer is A: Administer bronchodilators. In an acute asthma attack, the priority is to open the airways and improve breathing. Bronchodilators work quickly to relax the muscles around the airways, allowing the client to breathe easier. Corticosteroids are used for long-term control, not immediate relief. Oxygen therapy may be needed if the client's oxygen levels are low. Pain medication is not indicated for an acute asthma attack as the primary issue is airway constriction, not pain. Administering bronchodilators first helps address the immediate breathing difficulty in an asthma attack.

Correct Answer: B

Rationale: The correct answer is B: Vitamin B12. Strict vegetarians, especially those who exclude all animal products, are at risk of Vitamin B12 deficiency as it is primarily found in animal products. Vitamin C (A) deficiency is more common in those with poor fruit and vegetable intake. Vitamin E (C) deficiency is rare and usually seen in individuals with specific medical conditions. Magnesium (D) deficiency can occur in individuals with poor dietary intake or certain medical conditions, but it is not the primary concern for strict vegetarians.

Correct Answer: B

Rationale: The correct answer is B because moving the wheelchair close and pivoting on the unaffected extremity is the safest way to transfer a client with hemiparesis. This method minimizes strain on the affected side and reduces the risk of falls. First, ensure the wheelchair is positioned close to the bed. Then, assist the client to pivot by placing weight on the unaffected side and using proper body mechanics. This technique maintains stability and prevents injury. Choice A is incorrect because standing and walking the client to the wheelchair puts excessive strain on the affected side, increasing the risk of falls. Choice C is incorrect as pivoting on the affected extremity can lead to injury and instability. Choice D is incorrect as having the client stand and push to the wheelchair can be dangerous and may cause further harm.
