1. 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.

2. What is the appropriate needle size for insulin injection?

A. 18G, 1 ½” long
B. 22G, 1” long
C. 22G, 1 ½” long
D. 25G, 5/8” long

Correct answer: D

Rationale: The appropriate needle size for insulin injection is 25G, 5/8” long. This size allows for accurate and comfortable insulin administration in subcutaneous tissue.

3. Which of the following is included in Orem’s theory?

A. Maintenance of a sufficient intake of air
B. Self-perception
C. Love and belonging
D. Physiological needs

Correct answer: A

Rationale: Orem's theory, also known as the Self-Care Deficit Nursing Theory, focuses on individuals' ability to perform self-care to maintain health and well-being. One specific component of this theory is the maintenance of a sufficient intake of air, which is crucial for sustaining life and overall health. Option A is the correct choice as it directly relates to meeting physiological needs, such as the intake of air, to support optimal functioning and health. Choices B, C, and D are incorrect as they do not specifically align with Orem's emphasis on self-care and meeting physiological requirements.

4. Which of the following statements is incorrect about a patient with dysphagia?

A. The patient will find pureed or soft foods, such as custards, easier to swallow than water
B. Fowler’s or semi Fowler’s position reduces the risk of aspiration during swallowing
C. The patient should always feed himself
D. The nurse should perform oral hygiene before assisting with feeding

Correct answer: C

Rationale: The incorrect statement is that 'The patient should always feed himself.' Patients with dysphagia may require assistance with feeding due to difficulty in swallowing safely. It is essential to provide appropriate support and supervision during meal times to prevent complications such as aspiration or inadequate nutrition intake.

5. When planning care for a client with severe acute respiratory distress syndrome (SARS), which of the following actions should not be included in the care plan?

A. Administer antibiotics
B. Provide supplemental oxygen
C. Administer antiviral medications
D. Administer bronchodilators

Correct answer: A

Rationale: Severe acute respiratory distress syndrome (SARS) is caused by a virus, not bacteria, and antibiotics are ineffective against viral infections. Therefore, administering antibiotics would not be appropriate in the care plan for a client with SARS. The priority interventions for SARS include providing supplemental oxygen to improve oxygenation, administering antiviral medications to target the viral infection, and using bronchodilators to help with bronchospasm or airway constriction. Antibiotics are not indicated unless there is a secondary bacterial infection present.
