Nursing Elites

1. The nurse administers an antibiotic for a respiratory tract infection. To evaluate the medication's effectiveness, which laboratory values should the nurse monitor?

• A. Platelet count and red blood cell count.
• B. White blood cell count and sputum culture.
• C. Hemoglobin A1c and glucose tolerance test.
• D. Arterial blood gases and serum electrolytes.

Correct answer: B

Rationale: The correct answer is B: White blood cell count and sputum culture. Monitoring white blood cell count and sputum cultures is essential to assess the effectiveness of the antibiotic in treating the respiratory tract infection. Changes in white blood cell count can indicate the body's response to infection, while sputum cultures help determine if the antibiotic is targeting the specific pathogens causing the infection. Choices A, C, and D are incorrect because platelet count, red blood cell count, hemoglobin A1c, glucose tolerance test, arterial blood gases, and serum electrolytes are not directly related to evaluating the effectiveness of an antibiotic in treating a respiratory tract infection.

2. A client with chronic heart failure is admitted with worsening dyspnea. What is the nurse's priority action?

• A. Administer oxygen at 2 liters per nasal cannula.
• B. Administer a diuretic as prescribed.
• C. Assess the client's lung sounds.
• D. Reposition the client to relieve dyspnea.

Correct answer: A

Rationale: In a client with chronic heart failure experiencing worsening dyspnea, the priority action for the nurse is to administer oxygen at 2 liters per nasal cannula. This helps improve oxygenation and alleviate respiratory distress. Administering a diuretic (Choice B) may be necessary but addressing oxygenation comes first. While assessing lung sounds (Choice C) is important, it is not the immediate priority when the client is in respiratory distress. Repositioning the client (Choice D) may help with comfort but does not address the underlying issue of inadequate oxygenation.

3. A client with hypocalcemia is receiving calcium gluconate. What assessment finding requires immediate intervention?

• A. Decreased deep tendon reflexes.
• B. Wheezing and stridor.
• C. Decreased bowel sounds.
• D. Positive Chvostek's sign.

Correct answer: B

Rationale: Wheezing and stridor may indicate a severe allergic reaction to calcium gluconate, such as anaphylaxis, which requires immediate intervention. While hypocalcemia can present with decreased deep tendon reflexes and positive Chvostek's sign, these findings do not indicate an immediate life-threatening situation. Decreased bowel sounds are not directly related to a severe reaction to calcium gluconate and do not require immediate intervention.

4. During an initial assessment, a healthcare provider notes that a client has elevated blood pressure. Which of the following findings is considered a major risk factor for coronary artery disease?

• A. Elevated HDL cholesterol
• B. Low LDL cholesterol
• C. Elevated blood pressure
• D. Low triglyceride levels

Correct answer: C

Rationale: Elevated blood pressure is a significant risk factor for coronary artery disease because it increases the strain on the arteries, leading to potential damage and a higher risk of developing coronary artery disease. Elevated HDL cholesterol (Choice A) is actually considered beneficial as it helps reduce the risk of heart disease. Low LDL cholesterol (Choice B) is also beneficial as high levels of LDL are associated with an increased risk of coronary artery disease. Low triglyceride levels (Choice D) are not typically considered a major risk factor for coronary artery disease.

5. A client with chronic obstructive pulmonary disease (COPD) is being discharged home. What should the nurse include in the discharge teaching?

• A. Limit fluid intake to prevent lung congestion
• B. Avoid all physical activity to conserve energy
• C. Perform pursed-lip breathing during activities
• D. Increase oxygen flow rate if shortness of breath occurs

Correct answer: C

Rationale: The correct answer is C. Pursed-lip breathing helps control breathing and improves oxygen exchange in clients with COPD. It can ease shortness of breath during activities and should be included in discharge teaching to manage symptoms. Option A is incorrect as adequate fluid intake is important for thinning mucus in COPD. Option B is wrong as physical activity, as tolerated, is beneficial for COPD patients. Option D is also incorrect because changing oxygen flow rate without healthcare provider guidance can be dangerous.
