1. When planning care for a client on mechanical ventilation, which mode of ventilation that increases the effort of the client's respiratory muscles should NOT be included in the plan of care?

• A. Assist-control
• B. Synchronized intermittent mandatory ventilation
• C. Continuous positive airway pressure
• D. Pressure support ventilation

Correct answer: A

Rationale: Assist-control ventilation mode delivers a preset tidal volume at a set rate; however, it may not be suitable for clients who need to maintain some level of respiratory muscle activity. This mode provides full support for each breath, potentially leading to decreased respiratory muscle strength over time. Therefore, it is important to avoid using assist-control mode for clients who require increased effort of respiratory muscles to prevent muscle atrophy and promote optimal respiratory function.

2. The physician orders 10 gr of aspirin for a patient. The equivalent dose in milligrams is:

• A. 0.6 mg
• B. 10 mg
• C. 60 mg
• D. 600 mg

Correct answer: D

Rationale: To convert grains (gr) to milligrams (mg), you multiply by 60. Therefore, 10 gr of aspirin is equal to 600 mg (10 gr x 60 = 600 mg). So, the correct answer is 600 mg.

3. Which natural body defense plays an active role in preventing infection?

• A. Yawning
• B. Body hair
• C. Hiccupping
• D. Rapid eye movements

Correct answer: B

Rationale: Body hair plays an active role in preventing infection by acting as a filter to block pathogens. It helps to prevent harmful substances from entering the body through the skin, providing a physical barrier against potential infections.

4. During the assessment of a client receiving packed RBCs, which finding indicates fluid overload?

• A. Low back pain.
• B. Dyspnea.
• C. Hypotension.
• D. Thready pulse.

Correct answer: B

Rationale: Dyspnea is a key finding indicating fluid overload in a client receiving packed RBCs. Fluid overload can lead to pulmonary edema, causing difficulty breathing or shortness of breath (dyspnea). Low back pain is not typically associated with fluid overload but can be more related to musculoskeletal issues. Hypotension and thready pulse are more indicative of hypovolemia (low fluid volume), not fluid overload.

5. A healthcare professional is reviewing ABG laboratory results of a client who is in respiratory distress. The results are pH 7.47, PaCO2 32 mm Hg, and HCO3 22 mm Hg. The healthcare professional should recognize that the client is experiencing which of the following acid-base imbalances?

• A. Respiratory acidosis
• B. Respiratory alkalosis
• C. Metabolic acidosis
• D. Metabolic alkalosis

Correct answer: B

Rationale: The ABG results show a high pH (alkalosis) along with low PaCO2 and normal HCO3 levels, indicating respiratory alkalosis. In this condition, there is excessive loss of carbon dioxide (as seen by the low PaCO2) leading to a decrease in carbonic acid concentration and subsequent increase in pH. Metabolic acidosis or alkalosis would involve primary changes in bicarbonate levels, which are not predominant in this case.
