HESI Fundamentals Study Guide
1. A client with a history of chronic renal failure is admitted with generalized edema. Which laboratory value should the LPN/LVN monitor to assess the client's fluid balance?
- A. Serum potassium
- B. Serum calcium
- C. Serum albumin
- D. Serum sodium
Correct answer: C
Rationale: The correct answer is C, Serum albumin. In clients with chronic renal failure and generalized edema, monitoring serum albumin levels is crucial as it is a key indicator of fluid balance. Low serum albumin levels can contribute to edema formation due to decreased oncotic pressure, indicating fluid imbalance. Serum potassium (Choice A) is more related to kidney function and electrolyte balance in renal failure patients. Serum calcium (Choice B) is important for bone health but is not directly related to fluid balance. Serum sodium (Choice D) is more indicative of hydration status and electrolyte balance but may not directly reflect fluid balance in the context of chronic renal failure and edema.
2. The nurse is preparing to administer digoxin (Lanoxin) to a client with heart failure. Which assessment finding would prompt the nurse to withhold the medication and contact the healthcare provider?
- A. Heart rate of 55 beats per minute
- B. Blood pressure of 140/90 mmHg
- C. Respiratory rate of 20 breaths per minute
- D. Blood glucose level of 150 mg/dL
Correct answer: A
Rationale: A heart rate below 60 beats per minute is a contraindication for administering digoxin, as it can lead to bradycardia. Bradycardia is a common adverse effect associated with digoxin toxicity. Blood pressure of 140/90 mmHg, respiratory rate of 20 breaths per minute, and blood glucose level of 150 mg/dL are within normal limits and would not warrant withholding the medication or contacting the healthcare provider in this context. Therefore, a heart rate of 55 beats per minute would prompt the nurse to withhold digoxin and notify the healthcare provider.
3. A healthcare professional is preparing to administer an intramuscular injection to a client. Which site is most appropriate for the healthcare professional to use?
- A. Deltoid muscle
- B. Ventrogluteal site
- C. Dorsogluteal site
- D. Rectus femoris site
Correct answer: B
Rationale: The ventrogluteal site is the most appropriate site for administering an intramuscular injection to an adult client. This site is preferred due to its large muscle mass and distance from major nerves and blood vessels, reducing the risk of injury or complications. The deltoid muscle, while commonly used for vaccinations, may not be suitable for certain medications due to its smaller muscle mass. The dorsogluteal site is no longer recommended due to the proximity of the sciatic nerve, which can lead to complications. The rectus femoris site is not commonly used for intramuscular injections in clinical practice.
4. When providing oral care for an unconscious client, which of the following actions should the nurse take?
- A. Place the client in a lateral position with the head turned to the side before beginning the procedure.
- B. Insert a suction catheter before brushing the teeth.
- C. Use a soft-bristled toothbrush only with water.
- D. Brush the client's teeth while they are in a supine position.
Correct answer: A
Rationale: When providing oral care for an unconscious client, it is essential to place them in a lateral position with the head turned to the side before beginning the procedure. This positioning helps prevent aspiration by allowing fluids to drain out of the mouth, reducing the risk of choking or aspiration pneumonia. Inserting a suction catheter before brushing the teeth (Choice B) is not recommended as it can cause discomfort and increase the risk of oral tissue injury. Using a soft-bristled toothbrush only with water (Choice C) is not sufficient for effective oral care as toothpaste helps in removing plaque and bacteria. Brushing the client's teeth while they are in a supine position (Choice D) is not safe as it increases the risk of aspiration since fluids can easily enter the airway in this position.
5. 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.
