Nursing Elites

1. A client is hospitalized with heart failure (HF). Which intervention should the nurse implement to improve ventilation and reduce venous return?

• A. Perform passive range of motion exercises
• B. Place the client in high Fowler's position
• C. Administer oxygen via nasal cannula
• D. Increase the client's activity level

Correct answer: B

Rationale: In clients with heart failure, placing them in high Fowler's position is beneficial as it helps reduce venous return and improve ventilation. This position aids in decreasing the workload on the heart by promoting better lung expansion and oxygenation. Passive range of motion exercises (Choice A) are not directly related to improving ventilation or reducing venous return. Administering oxygen via nasal cannula (Choice C) may help with oxygenation but does not directly address reducing venous return. Increasing the client's activity level (Choice D) may worsen heart failure symptoms by increasing the workload on the heart.

2. Which of the following lab values would be most concerning in a patient receiving heparin therapy?

• A. Elevated hemoglobin levels.
• B. Low platelet count.
• C. High potassium levels.
• D. Low sodium levels.

Correct answer: B

Rationale: A low platelet count is most concerning in patients receiving heparin therapy due to the risk of heparin-induced thrombocytopenia. Heparin can sometimes cause a drop in platelet count, leading to a potentially serious condition where blood does not clot as it should. This can result in excessive bleeding or clot formation in blood vessels. Elevated hemoglobin levels, high potassium levels, and low sodium levels are not typically associated with heparin therapy and are less likely to cause immediate concerns or complications in this context.

3. The nurse is caring for a patient who is receiving an intravenous antibiotic. The nurse notes that the provider has ordered serum drug peak and trough levels. The nurse understands that these tests are necessary for which type of drugs?

• A. Drugs with a broad spectrum
• B. Drugs with a narrow spectrum
• C. Drugs with a broad therapeutic index
• D. Drugs with a narrow therapeutic index

Correct answer: D

Rationale: Medications with a narrow therapeutic index have a limited range between the therapeutic dose and a toxic dose. It is important to monitor these medications closely by evaluating regular serum peak and trough levels. Drugs with a narrow spectrum (Choice B) are antibiotics that target only a limited group of bacteria, not related to the need for peak and trough monitoring. Drugs with a broad spectrum (Choice A) cover a wide range of bacteria, but this characteristic does not determine the need for peak and trough monitoring. Drugs with a broad therapeutic index (Choice C) have a wide safety margin between therapeutic and toxic doses, so they typically do not require peak and trough level monitoring.

4. A nurse reviews a female client’s laboratory results. Which result from the client’s urinalysis should the nurse recognize as abnormal?

• A. pH 5.6
• B. Ketone bodies present
• C. Specific gravity of 1.020
• D. Clear and yellow color

Correct answer: B

Rationale: The correct answer is B: Ketone bodies present. Ketone bodies in urine indicate abnormal metabolism, specifically the incomplete breakdown of fatty acids. Normally, there should be no ketones present in urine. Ketone bodies are produced when the body uses fat sources instead of glucose for cellular energy. A pH range between 4.6 and 8, a specific gravity between 1.005 and 1.030, and clear yellow color in urine are considered normal findings for a female client’s urinalysis. Therefore, options A, C, and D are within normal ranges and not indicative of abnormal results in the urinalysis.

5. A client with a history of lung disease is at risk for respiratory acidosis. For which of the following signs and symptoms does the nurse assess this client?

• A. Disorientation and dyspnea
• B. Drowsiness, headache, and tachypnea
• C. Tachypnea, dizziness, and paresthesias
• D. Dysrhythmias and decreased respiratory rate and depth

Correct answer: A

Rationale: The correct answer is A: Disorientation and dyspnea. In respiratory acidosis, the retention of carbon dioxide leads to an increase in carbonic acid, causing the pH of the blood to decrease. This can result in symptoms such as dyspnea (difficulty breathing) due to hypoxia and disorientation due to the effects of hypercapnia (elevated carbon dioxide levels) on the brain. Choice B is incorrect because while drowsiness and tachypnea can be present in respiratory acidosis, headache is not a common symptom. Choice C is incorrect because dizziness and paresthesias are not typical symptoms of respiratory acidosis. Choice D is incorrect because dysrhythmias and a decreased respiratory rate and depth are more commonly associated with respiratory alkalosis, not respiratory acidosis.
