Practice HESI Fundamentals Exam Questions
Question 1 of 5
A client has an indwelling urinary catheter. Which of the following actions should the nurse take to prevent infection?
Correct Answer: B
Rationale: Cleaning the perineal area with antiseptic solution daily is essential to prevent infection when caring for a client with an indwelling urinary catheter. This practice helps reduce the risk of introducing pathogens into the urinary tract. Ensuring the catheter tubing is free of kinks (Choice A) is important for maintaining proper urine flow but is not directly related to preventing infection. Irrigating the catheter with normal saline every shift (Choice C) is not a routine practice and can increase the risk of introducing pathogens. Securing the catheter to the client's leg (Choice D) is important for stability but does not directly prevent infection.
Question 2 of 5
A healthcare provider is monitoring a client for adverse effects following the administration of an opioid. Which of the following effects should the provider identify as an adverse effect of opioids?
Correct Answer: D
Rationale: The correct answer is D: Orthostatic hypotension. Opioids can cause orthostatic hypotension, leading to a sudden drop in blood pressure when changing positions. This effect is due to the vasodilatory properties of opioids, which can result in decreased blood flow to the brain upon standing up. Choices A, B, and C are incorrect. Urinary incontinence and diarrhea are not typical adverse effects of opioids. Bradypnea, or slow breathing, is a potential side effect of opioid overdose or respiratory depression, but it is not a common adverse effect following normal opioid administration.
Question 3 of 5
A client with a history of hypertension is prescribed a diuretic. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the medication?
Correct Answer: B
Rationale: The correct answer is to monitor serum potassium levels. When a client is prescribed a diuretic, monitoring serum potassium levels is essential to evaluate the medication's effectiveness and to detect potential electrolyte imbalances. Diuretics can cause potassium loss, leading to hypokalemia, which can have serious consequences such as cardiac arrhythmias. Monitoring serum calcium levels (Choice A) is not typically required when assessing the effectiveness of diuretics. Similarly, monitoring serum sodium levels (Choice C) is important for other conditions but is not the primary concern when evaluating diuretic therapy. Monitoring serum magnesium levels (Choice D) is also important, but potassium levels are more critical in assessing diuretic effectiveness and preventing complications.
Question 4 of 5
When assessing a client reporting increased pain after physical therapy, which question should the nurse ask to evaluate the quality of the pain?
Correct Answer: A
Rationale: The correct question to ask when assessing the quality of a client's pain is whether the pain is sharp or dull. This helps in understanding the characteristics of the pain being experienced. Choice B, asking if the pain radiates to other areas, focuses more on pain distribution rather than quality. Choice C, inquiring if the pain increases with movement, pertains to aggravating factors rather than pain quality. Choice D, requesting the client to rate pain on a scale of 1 to 10, is related to pain intensity rather than quality.
Question 5 of 5
A nurse is preparing to administer ketorolac 0.5 mg/kg IV bolus every 6 hr to a school-age child who weighs 66 lb. The available ketorolac injection is 30 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale: To calculate the dose, first convert the weight from pounds to kilograms. The child weighs 66 lb, which is approximately 30 kg. The prescribed dose is 0.5 mg/kg, so for a 30 kg child, the dose would be 0.5 mg/kg x 30 kg = 15 mg. Since the available ketorolac injection is 30 mg/mL, the nurse should administer 15 mg · 30 mg/mL = 0.5 mL per dose. Therefore, choice A (0.5 mL) is the correct answer. Choices B, C, and D are incorrect as they do not accurately calculate the correct dose based on the child's weight and the concentration of the ketorolac injection.
