Nursing Elites

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. Which of the following vascular system changes result from aging?

• A. Increased peripheral resistance of the blood vessels
• B. Decreased blood flow
• C. Increased workload of the left ventricle
• D. All of the above

Correct answer: D

Rationale: As individuals age, various changes occur in the vascular system. These changes include increased peripheral resistance of the blood vessels, decreased blood flow, and an increased workload of the left ventricle. Therefore, all the listed changes result from aging, making option D, 'All of the above,' the correct answer.

3. A client experiencing acute dyspnea and diaphoresis reports anxiety and difficulty breathing. Vital signs include HR 117/min, respirations 38/min, temperature 38.4 C (101.2 F), and blood pressure 100/54 mm Hg. What should the nurse prioritize?

• A. Notify the provider.
• B. Administer heparin via IV infusion.
• C. Administer oxygen therapy.
• D. Obtain a spiral CT scan.

Correct answer: C

Rationale: In a client with acute dyspnea, diaphoresis, tachycardia, tachypnea, fever, and hypotension, the priority is to ensure adequate oxygenation. Administering oxygen therapy helps improve oxygenation levels and stabilize the client's condition. This intervention takes precedence over notifying the provider, administering heparin, or obtaining a CT scan, as oxygen therapy addresses the client's immediate need for respiratory support.

4. When providing discharge teaching for a group of clients, a nurse should recommend a referral to a dietitian for which client?

• A. A client who has a prescription for warfarin and states, 'I will need to limit how much spinach I eat.'
• B. A client who has gout and states, 'I can continue to eat anchovies on my pizza.'
• C. A client who has a prescription for spironolactone and states, 'I will reduce my intake of foods that contain potassium.'
• D. A client who has osteoporosis and states, 'I'll plan to take my calcium carbonate with a full glass of water.'

Correct answer: B

Rationale: The correct answer is the client who has gout and states, 'I can continue to eat anchovies on my pizza.' Gout is a condition that requires dietary modifications to manage symptoms. Anchovies are high in purines, which can exacerbate gout symptoms. Therefore, a referral to a dietitian is essential to provide appropriate dietary guidance for a client with gout. Clients on warfarin may need to monitor their vitamin K intake, particularly from foods like spinach. Clients taking spironolactone should be cautious about potassium-rich foods. Clients with osteoporosis should be educated on the proper administration of calcium supplements but do not necessarily need a dietitian referral for this specific statement.

5. A client in the emergency department is experiencing an acute asthma attack. Which assessment indicates an improvement in respiratory status?

• A. SaO2 95%
• B. Wheezing
• C. Retraction of sternal muscles
• D. Premature ventricular complexes (PVC's)

Correct answer: A

Rationale: An SaO2 of 95% indicates an improvement in the client's oxygen saturation, suggesting better respiratory status. In asthma exacerbation, a decrease in SaO2 levels would signal worsening respiratory distress. Wheezing, retraction of sternal muscles, and premature ventricular complexes are indicators of respiratory compromise and worsening respiratory status in acute asthma attacks. Monitoring SaO2 levels is crucial in assessing the effectiveness of interventions and guiding treatment decisions.
