Extract:
Question 1 of 5
A nurse is collecting data from a client who has heart failure and takes chlorothiazide sodium. Which of the following findings should the nurse identify as indicating hypokalemia?
Correct Answer: B
Rationale: Hypokalemia impairs neuromuscular function, leading to muscle weakness and decreased deep-tendon reflexes, which is a key clinical finding.
Question 2 of 5
A nurse is reviewing the laboratory values for a client who has heart failure and is taking bumetanide. For which of the following results should the nurse notify the provider?
Correct Answer: C
Rationale: A potassium level of 2.3 mEq/L is critically low, and bumetanide, a loop diuretic, can cause hypokalemia, which may lead to dangerous cardiac dysrhythmias, necessitating immediate notification.
Question 3 of 5
A nurse is caring for a client who reports an area of redness, warmth, tenderness and pain in the right calf. Which of the following actions should the nurse anticipate when notifying the provider of this finding?
Correct Answer: D
Rationale: A venous duplex ultrasound is the appropriate diagnostic test to confirm a suspected deep vein thrombosis (DVT), which is suggested by the client's symptoms.
Question 4 of 5
A nurse is preparing to administer potassium chloride 20 mEq. The amount available is potassium chloride liquid 40 mEq/15 mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 7.5
Rationale:
To calculate: (20 mEq / 40 mEq) × 15 mL = 7.5 mL, which is the correct dose to administer.
Question 5 of 5
A nurse is reinforcing teaching to a client who has dilated cardiomyopathy (DCM). Which of the following statements by the nurse should be included in the teaching?
Correct Answer: B
Rationale: Dilated cardiomyopathy involves excessive stretching and thinning of the ventricular walls, impairing contraction, which is the correct description.
