HESI LPN
Fundamentals HESI
1. A client with a history of atrial fibrillation is receiving warfarin (Coumadin). Which laboratory value should the LPN/LVN monitor closely while the client is taking this medication?
- A. Blood glucose level
- B. Prothrombin time (PT) and INR
- C. Serum potassium level
- D. Serum creatinine level
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.
2. During auscultation of a client experiencing chest pain worsened by inspiration, a nurse hears a high-pitched scratching sound in both systole and diastole with the diaphragm of the stethoscope placed at the left sternal border. Which of the following heart sounds should the nurse document?
- A. Pericardial friction rub
- B. Murmur
- C. S1 and S2
- D. Bruit
Correct answer: A
Rationale: The correct answer is 'Pericardial friction rub.' A pericardial friction rub is a high-pitched, scratching sound heard in both systole and diastole, which is characteristic of pericardial inflammation. This sound is different from a murmur, which is a swooshing or blowing sound due to turbulent blood flow. S1 and S2 are normal heart sounds, and a bruit is a whooshing sound caused by turbulent blood flow in an artery, not related to pericardial inflammation.
3. The client is being instructed on how to collect a clean catch urine specimen. Which sequence is appropriate for teaching?
- A. Void a little, clean the meatus, then collect specimen
- B. Clean the meatus, begin voiding, then catch urine stream
- C. Clean the meatus, then urinate into container
- D. Void continuously and catch some of the urine
Correct answer: B
Rationale: The correct sequence for obtaining a clean catch urine specimen involves first cleaning the meatus to prevent contamination, then initiating voiding to catch the midstream urine. This method ensures that the sample is as uncontaminated as possible, making choice B the correct sequence. Option A is incorrect as cleaning the meatus should be done before voiding. Option C is incorrect as it does not involve catching a midstream urine sample. Option D is incorrect as it suggests catching urine throughout the entire voiding process, which may lead to contamination.
4. A client has right-sided paralysis following a cerebrovascular accident. Which of the following prescriptions should the nurse anticipate to prevent a plantar flexion contracture of the affected extremity?
- A. Ankle-foot orthotic
- B. Continuous passive motion machine
- C. Abduction splint
- D. Sequential compression device
Correct answer: A
Rationale: An ankle-foot orthotic is the correct choice to prevent a plantar flexion contracture in a paralyzed limb. An ankle-foot orthotic helps maintain proper alignment of the foot and ankle, preventing the foot from being permanently fixed in a pointed-down position. Continuous passive motion machines are typically used to promote joint movement after surgery and would not address the prevention of contractures in this case. Abduction splints are used to keep the legs apart and would not address the specific issue described. Sequential compression devices are used to prevent deep vein thrombosis by promoting circulation in the lower extremities and are not indicated for preventing plantar flexion contractures.
5. When using an open irrigation technique to irrigate a client's indwelling urinary catheter, which of the following actions should the nurse take?
- A. Place the client in a side-lying position
- B. Instill 15 mL of irrigation fluid into the catheter with each flush
- C. Subtract the amount of irrigant used from the client's urine output
- D. Perform the irrigation using a 20 mL syringe
Correct answer: C
Rationale: The correct action for the nurse to take when using an open irrigation technique on a client with an indwelling urinary catheter is to subtract the amount of irrigant used from the client's urine output. This calculation helps ensure an accurate measurement of the client's actual urine output by accounting for the irrigation fluid introduced into the catheter. Placing the client in a side-lying position (Choice A) is not directly related to the irrigation procedure. Instilling a specific volume of irrigation fluid (Choice B) may vary depending on the client's condition and the healthcare provider's order. Using a 20 mL syringe for irrigation (Choice D) is a matter of equipment choice and does not directly impact the calculation of urine output in this context.
