HESI RN Nursing Leadership and Management Exam 6
1. A healthcare professional reviews a client's electrolyte laboratory report and notes that the potassium level is 3.2 mEq/L. Which of the following would the healthcare professional note on the electrocardiogram as a result of the laboratory value?
- A. U waves
- B. Absent P waves
- C. Elevated T waves
- D. Elevated ST segment
Correct answer: A
Rationale: The correct answer is A: U waves. A low potassium level (hypokalemia) can manifest as U waves on an ECG. U waves are small, extra deflections seen after the T wave and may indicate cardiac irritability. Absent P waves (Choice B) are associated with conditions like atrial fibrillation. Elevated T waves (Choice C) can be seen in hyperkalemia, not hypokalemia. Elevated ST segment (Choice D) is not typically associated with low potassium levels but can be seen in conditions like myocardial infarction.
2. A client with type 1 diabetes is admitted with diabetic ketoacidosis (DKA). Which clinical finding requires immediate intervention?
- A. Serum glucose of 300 mg/dL
- B. Serum potassium of 5.5 mEq/L
- C. Serum bicarbonate of 18 mEq/L
- D. Positive urine ketones
Correct answer: C
Rationale: A serum bicarbonate level of 18 mEq/L indicates metabolic acidosis in a client with DKA, requiring immediate intervention. In DKA, the body produces excess ketones, leading to metabolic acidosis, which is reflected by a low serum bicarbonate level. Correcting the low serum bicarbonate is crucial to normalize the metabolic acidosis and improve the client's condition. While elevated serum glucose (choice A) and urine ketones (choice D) are characteristic of DKA, addressing the metabolic acidosis takes precedence. Serum potassium (choice B) levels may also need monitoring and management, but correcting the acidosis is the priority to prevent complications like cardiovascular collapse.
3. Phenazopyridine hydrochloride (Pyridium) is prescribed for a client for symptomatic relief of pain resulting from a lower urinary tract infection. The nurse reinforces to the client:
- A. To take the medication after meals
- B. To take the medication before meals
- C. To discontinue the medication if a headache occurs
- D. That a reddish-orange discoloration of the urine may occur
Correct answer: D
Rationale: The nurse should instruct the client that a reddish-orange discoloration of urine may occur. The nurse should also educate the client that this discoloration can stain fabric. It is recommended to take the medication after meals to reduce the possibility of gastrointestinal upset. While a headache is an occasional side effect of the medication, it does not warrant discontinuation of the medication.
4. During an excretory urogram, which observation made by the nurse indicates a complication?
- A. The client complains of a salty taste in the mouth when the dye is injected
- B. The client's entire body turns a bright red color
- C. The client states 'I have a feeling of getting warm.'
- D. The client gags and complains 'I am getting sick.'
Correct answer: B
Rationale: The observation of the client's entire body turning a bright red color during an excretory urogram indicates a severe reaction to the dye, which is a significant complication. This reaction is likely due to an allergic response and requires immediate medical attention. The other choices do not signify a severe complication: choice A could be a normal taste sensation related to the procedure, choice C may indicate a mild reaction, and choice D could be a common side effect of nausea without indicating a severe complication requiring immediate intervention.
5. A client with atrial fibrillation is prescribed warfarin, and their INR is elevated. What is the nurse's priority action?
- A. Administer a dose of vitamin K to reverse the effects of warfarin.
- B. Monitor the client for signs of bleeding, such as bruising or nosebleeds.
- C. Increase the client’s warfarin dosage to prevent clot formation.
- D. Notify the healthcare provider immediately and hold the next dose of warfarin.
Correct answer: D
Rationale: An elevated INR in clients taking warfarin increases the risk of bleeding, indicating the dose may be too high. The nurse's priority action is to notify the healthcare provider immediately and hold the next dose of warfarin to prevent bleeding complications. Administering vitamin K is not the first-line intervention for an elevated INR. Monitoring for signs of bleeding is important but not the priority over contacting the healthcare provider. Increasing the warfarin dosage can exacerbate the risk of bleeding and is contraindicated.
