What is the primary action of a short-acting beta2-agonist (SABA) prescribed to a patient with an acute asthma exacerbation?
- A. Reduce inflammation
- B. Relieve bronchospasm
- C. Thin respiratory secretions
- D. Suppress cough
Correct Answer: B
Rationale: The correct answer is B: Relieve bronchospasm. Short-acting beta2-agonists (SABAs) like albuterol act by stimulating beta2 receptors in the airway smooth muscle, leading to bronchodilation and relieving bronchospasm. This helps to quickly open up the airways during an acute asthma exacerbation. Choice A is incorrect because SABAs do not directly reduce inflammation. Choice C is incorrect as SABAs do not affect respiratory secretions. Choice D is incorrect as SABAs do not suppress cough but rather target bronchospasm.

A patient with hyperlipidemia is prescribed atorvastatin. What lab test should be monitored periodically to assess for adverse effects?
- A. Liver function tests
- B. Complete blood count
- C. Blood glucose levels
- D. Serum potassium
Correct Answer: A
Rationale: Step-by-step rationale:
1. Atorvastatin is a statin medication commonly known to potentially cause liver damage.
2. Monitoring liver function tests periodically helps assess for any liver abnormalities.
3. Elevated liver enzymes may indicate liver injury from atorvastatin.
4. Monitoring liver function tests allows for early detection and management of adverse effects.
Summary:
A: Monitoring liver function tests is crucial due to atorvastatin's potential hepatotoxicity.
B: Complete blood count is not typically affected by atorvastatin.
C: Blood glucose levels are not directly related to atorvastatin use.
D: Serum potassium is not specifically monitored for atorvastatin-related adverse effects.
A patient with rheumatoid arthritis is prescribed methotrexate. What should the nurse include in the patient teaching?
- A. Take folic acid supplements as prescribed.
- B. Avoid alcohol completely.
- C. Expect to see immediate results.
- D. Limit fluid intake to 1 liter per day.
Correct Answer: A
Rationale: The correct answer is A: Take folic acid supplements as prescribed. Methotrexate can lead to folic acid deficiency, so supplementing with folic acid helps prevent side effects. It is important for the nurse to educate the patient on the importance of taking folic acid to maintain overall health.
Choice B is incorrect. While it is generally recommended to limit alcohol consumption with methotrexate, avoiding it completely may not be necessary for all patients.
Choice C is incorrect. Methotrexate takes time to work, often several weeks to months, so immediate results should not be expected.
Choice D is incorrect. Limiting fluid intake to 1 liter per day is not a standard recommendation for patients taking methotrexate. Adequate hydration is important for overall health.
The healthcare professional is caring for a client with heart failure who is receiving digoxin (Lanoxin). Which assessment finding requires immediate intervention?
- A. Heart rate of 58 beats per minute.
- B. Nausea and vomiting.
- C. Blood pressure of 130/80 mm Hg.
- D. Shortness of breath.
Correct Answer: B
Rationale: The correct answer is B: Nausea and vomiting. This finding requires immediate intervention because digoxin toxicity can present with gastrointestinal symptoms like nausea and vomiting. This can indicate an overdose of digoxin, which can be life-threatening. Prompt action is necessary to prevent further complications.
A: Heart rate of 58 beats per minute is within the therapeutic range for digoxin and does not require immediate intervention.
C: Blood pressure of 130/80 mm Hg is also within normal limits and does not indicate an urgent issue.
D: Shortness of breath can be a symptom of heart failure but is not a direct indication of digoxin toxicity requiring immediate intervention.
A 75-year-old patient is admitted for pancreatitis. Which tool would be the most appropriate for the nurse to use during the admission assessment?
- A. Drug Abuse Screening Test (DAST-10)
- B. Clinical Institute Withdrawal Assessment of Alcohol Scale, Revised (CIWA-Ar)
- C. Screening Test-Geriatric Version (SMAST-G)
- D. Mini-Mental State Examination
Correct Answer: C
Rationale: The most appropriate tool for the nurse to use during the admission assessment of a 75-year-old patient admitted for pancreatitis is the Screening Test-Geriatric Version (SMAST-G). This tool is specifically designed to assess for alcohol abuse in older adults, which is relevant in this case as alcohol consumption can be a risk factor for pancreatitis. The SMAST-G helps identify potential alcohol-related issues in the elderly population, allowing for appropriate interventions and care planning.
Rationale:
A: The Drug Abuse Screening Test (DAST-10) is not the most appropriate tool in this scenario as it focuses on broader drug abuse rather than specifically alcohol abuse.
B: The Clinical Institute Withdrawal Assessment of Alcohol Scale, Revised (CIWA-Ar) is used to assess for alcohol withdrawal symptoms, not alcohol abuse itself.
D: The Mini-Mental State Examination is used to assess cognitive function, which is not directly relevant to the admission assessment for pancreatitis in this case.
A patient with type 1 diabetes mellitus is admitted to the hospital with diabetic ketoacidosis (DKA). What is the priority nursing action?
- A. Administer regular insulin intravenously.
- B. Give oral hypoglycemic agents.
- C. Administer sodium bicarbonate.
- D. Provide a high-calorie diet.
Correct Answer: A
Rationale: The correct answer is A: Administer regular insulin intravenously. In DKA, the priority is to lower blood glucose levels and correct acidosis. Regular insulin intravenously is the fastest way to reduce blood glucose levels. Oral hypoglycemic agents (B) are not effective in DKA. Sodium bicarbonate (C) is not routinely recommended in DKA as it may worsen acidosis. Providing a high-calorie diet (D) is not appropriate as the focus should be on treating the underlying condition first.
