Nursing Elites

1. Following the diagnosis of angina pectoris, a client reports being unable to walk up two flights of stairs without pain. Which of the following measures would most likely help the client prevent this problem?

• A. Climb the stairs early in the day.
• B. Rest for at least an hour before climbing the stairs.
• C. Take a nitroglycerin tablet before climbing the stairs.
• D. Lie down after climbing the stairs.

Correct answer: C

Rationale: The correct answer is to take a nitroglycerin tablet before climbing the stairs. Nitroglycerin helps prevent angina by dilating the coronary arteries, which increases blood flow to the heart. This medication can help reduce the chest pain and discomfort experienced during physical exertion. Climing the stairs early in the day (Choice A) does not address the underlying issue of inadequate blood flow to the heart. Resting for at least an hour before climbing the stairs (Choice B) may not be as effective in preventing angina as taking nitroglycerin. Lying down after climbing the stairs (Choice D) does not offer a preventive measure for angina; it is more focused on post-activity rest rather than prevention.

2. What is the priority intervention for a patient with a suspected myocardial infarction (MI)?

• A. Administering oxygen.
• B. Administering nitroglycerin.
• C. Administering aspirin.
• D. Administering morphine.

Correct answer: A

Rationale: Administering oxygen is the priority intervention for a patient with a suspected myocardial infarction to improve oxygenation. Oxygen helps ensure an adequate oxygen supply to the heart muscle, reducing the workload on the heart. Nitroglycerin and aspirin are important interventions in the treatment of MI; however, oxygen administration takes precedence to ensure adequate oxygenation. Morphine may be considered for pain relief, but it is not the initial priority in the treatment of a suspected MI.

3. A client who underwent preadmission testing 1 week before surgery had blood drawn for several serum laboratory studies. Which abnormal laboratory results should the nurse report to the surgeon’s office? Select all that apply.

• A. Hematocrit 30%
• B. Sodium 141 mEq/L
• C. Hemoglobin 8.9 g/dL
• D. Platelets 210,000 cells/mm3

Correct answer: C

Rationale: The correct answer is C. Hemoglobin level of 8.9 g/dL is below the normal range, indicating anemia. Anemia can affect the body's ability to carry oxygen, impacting surgical outcomes. Hematocrit level is an indirect measure of red blood cells, which also reveals anemia when low. Sodium level of 141 mEq/L and platelet count of 210,000 cells/mm3 are within normal ranges and do not require immediate reporting. Abnormal sodium levels can lead to various issues, but in this scenario, it is not a concern for surgical readiness. Platelet count is vital for blood clotting, and a count of 210,000 cells/mm3 is considered normal, so it does not need urgent attention.

4. Which of the following medications is typically used to treat asthma?

• A. Aspirin
• B. Metformin
• C. Albuterol
• D. Lisinopril

Correct answer: C

Rationale: The correct answer is C, Albuterol. Albuterol is a bronchodilator commonly used to treat asthma by relaxing the muscles around the airways, helping to relieve symptoms such as coughing, wheezing, shortness of breath, and chest tightness. Aspirin (Choice A) is not typically used to treat asthma and can actually trigger asthma symptoms in some individuals. Metformin (Choice B) is a medication for managing type 2 diabetes and is not indicated for asthma treatment. Lisinopril (Choice D) is an angiotensin-converting enzyme (ACE) inhibitor primarily used to treat high blood pressure and heart failure, not asthma.

5. A client with histoplasmosis has the following arterial blood gas (ABG) results: pH 7.30, PCO2 58 mm Hg, PO2 75 mm Hg, HCO3 27 mEq/L. Which of the following acid-base disturbances does the nurse recognize in these results?

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

Correct answer: A

Rationale: The client's ABG results show a low pH (acidosis) and an elevated PCO2, indicating respiratory acidosis. In respiratory acidosis, there is inadequate excretion of CO2, leading to increased PCO2 levels and a decrease in pH. Therefore, the correct answer is 'Metabolic acidosis'. Choices B, C, and D are incorrect. Metabolic alkalosis is characterized by elevated pH and bicarbonate levels. Respiratory acidosis involves low pH and high PCO2 levels, as seen in this case. Respiratory alkalosis is associated with high pH and low PCO2 levels.
