1. The healthcare provider is caring for a client with jaundice. Which serum laboratory value is likely to be elevated for this client?
- A. Amylase
- B. Creatinine
- C. Blood urea nitrogen
- D. Bilirubin
Correct answer: D
Rationale: Bilirubin is a key serum laboratory value that is likely to be elevated in clients with jaundice. Jaundice is characterized by a yellowish discoloration of the skin and eyes due to an excess of bilirubin, a breakdown product of hemoglobin. Elevated amylase levels are associated with pancreatic conditions, not specifically jaundice. Creatinine and blood urea nitrogen are markers of kidney function and are not directly related to jaundice.
2. A client with a history of heart failure is admitted to the hospital with worsening dyspnea. The nurse notes that the client has a productive cough with pink, frothy sputum. What action should the nurse take first?
- A. Administer oxygen
- B. Perform chest physiotherapy
- C. Elevate the head of the bed
- D. Obtain a sputum specimen
Correct answer: A
Rationale: In a client with heart failure presenting with worsening dyspnea and pink, frothy sputum (indicating pulmonary edema), the priority action for the nurse is to administer oxygen. Oxygen therapy helps improve oxygenation and alleviate dyspnea by increasing the oxygen supply to the lungs. Performing chest physiotherapy, elevating the head of the bed, or obtaining a sputum specimen are not the initial actions indicated in this situation and may delay addressing the client's immediate need for improved oxygenation.
3. A 14-year-old girl with asthma complains of feeling nervous and jittery after a respiratory therapy bronchodilator treatment. What explanation is best for the nurse to provide to this adolescent?
- A. Nervousness should disappear when hypoxia is relieved after several bronchodilator treatments
- B. Tremors result from the rapid dilation of the bronchioles and an increased heart rate
- C. A fast heart rate and jitteriness are side effects of the bronchodilator treatment containing albuterol
- D. Excessive coughing, which causes tachypnea and anxiety, result from the use of bronchodilators
Correct answer: C
Rationale: The correct answer is C because a fast heart rate and jitteriness are common side effects of bronchodilators like albuterol. Choice A is incorrect as nervousness is more likely a side effect of the medication than solely related to hypoxia. Choice B is incorrect as it provides a partial explanation focusing only on tremors and heart rate, not mentioning jitteriness. Choice D is incorrect because excessive coughing and tachypnea are not typically associated with bronchodilator use; instead, they may indicate inadequate relief or other issues.
4. The nurse is performing a physical assessment of a client with a history of smoking and notes a barrel chest. Which action is most important for the nurse to take next?
- A. Assess the client's oxygen saturation level
- B. Teach the client pursed-lip breathing techniques
- C. Determine the client's history of lung disease
- D. Obtain an arterial blood gas sample
Correct answer: A
Rationale: Corrected Rationale: Assessing the client's oxygen saturation level is crucial when a nurse identifies a barrel chest. A barrel chest is often associated with chronic obstructive pulmonary disease (COPD), which can lead to impaired gas exchange and decreased oxygen saturation. Monitoring the oxygen saturation level will provide immediate information on the client's respiratory status. Teaching pursed-lip breathing techniques, determining lung disease history, and obtaining arterial blood gas samples are important interventions but assessing oxygen saturation takes precedence in this scenario due to its direct impact on the client's respiratory function.
5. A client in acute renal failure has a serum potassium of 7.5 mEq/L. Based on this finding, the nurse should anticipate implementing which action?
- A. Administer an IV of normal saline rapidly and NPH insulin subcutaneously.
- B. Administer a retention enema of Kayexalate.
- C. Add 40 mEq of KCL (potassium chloride) to the present IV solution.
- D. Administer a lidocaine bolus IV push.
Correct answer: B
Rationale: In acute renal failure with a high serum potassium level, the priority intervention is to lower potassium levels to prevent complications like cardiac arrhythmias. Administering a retention enema of Kayexalate is the correct action as it helps lower high potassium levels by exchanging sodium for potassium in the intestines. Options A, C, and D are incorrect. Administering normal saline rapidly and NPH insulin or adding more potassium to the IV solution can further increase potassium levels, worsening the condition. Lidocaine is not indicated for treating hyperkalemia.
