Fundamentals HESI

Correct Answer: C

Rationale: The correct answer is C: Rash, blood dyscrasias, and severe depression are serious side effects of haloperidol that necessitate withholding the dose and prompt further evaluation. Rash can indicate an allergic reaction, blood dyscrasias are serious blood disorders that can be life-threatening, and severe depression may worsen with haloperidol use. Choices A, B, and D are incorrect because drowsiness, lethargy, inactivity, dry mouth, nasal congestion, blurred vision, hyperglycemia, weight gain, and edema are common side effects of haloperidol that may not necessarily contraindicate its use but should be monitored and managed appropriately.

Correct Answer: B

Rationale: The correct answer is B: Crackles in the lungs. Crackles in the lungs indicate pulmonary congestion, a serious complication of left-sided heart failure. The presence of crackles suggests fluid accumulation in the lungs, impairing gas exchange and potentially leading to respiratory distress. Immediate intervention is necessary to prevent worsening respiratory function. Choices A, C, and D are incorrect: Peripheral edema is a common finding in heart failure but may not be as acutely concerning as pulmonary congestion. Jugular vein distention is associated with right-sided heart failure, not left-sided heart failure. Hepatomegaly is often seen in liver conditions and right-sided heart failure, not specifically left-sided heart failure.

Correct Answer: B

Rationale: The correct action for the nurse to include before an intravenous pyelogram is ensuring the client is free of metal objects. Metal objects can interfere with the imaging procedure and may need to be removed to prevent artifacts. Monitoring for pain in the suprapubic region (choice A) is not directly related to the procedure and is not a standard pre-procedure action. Administering oral contrast (choice C) is more common for other imaging studies like a CT scan, not an intravenous pyelogram. Assisting with a bowel cleansing (choice D) is not typically required before an intravenous pyelogram.

Correct Answer: B

Rationale: The LPN/LVN should closely monitor Prothrombin time (PT) and INR (Choice B) levels in a client receiving warfarin. These values are crucial to ensure the medication's effectiveness and prevent complications like bleeding. Monitoring blood glucose level (Choice A) is not directly relevant to warfarin therapy. While serum potassium level (Choice C) and serum creatinine level (Choice D) are important for other conditions or medications, they are not specifically required to be monitored when a client is on warfarin.

Correct Answer: B

Rationale: To calculate the correct dose of 15 mg, the LPN/LVN should administer 1.5 ml of Lasix (20 mg/2 ml). This calculation ensures precise dosing. Choice A (1 ml) is too low and would provide only 10 mg, while choice C (1.75 ml) and choice D (2 ml) would exceed the prescribed dose, resulting in potential adverse effects. It is important for the LPN/LVN to administer the exact prescribed dose to ensure therapeutic efficacy and avoid unnecessary complications.
