Question 1 of 5
The client has an order for Garamycin (gentamicin) to be administered. Which lab test should be done before beginning the medication?
Correct Answer: B
Rationale: Gentamicin, an aminoglycoside, is nephrotoxic. Serum creatinine is monitored before administration to assess baseline kidney function, as impaired renal function increases toxicity risk. Hematocrit, white cell count, and BUN are less specific for gentamicin.
Question 2 of 5
A client confides to the nurse that he tasted poison in his evening meal. This would be an example of what type of hallucination?
Correct Answer: B
Rationale: Auditory hallucinations involve sensory perceptions of hearing. Gustatory hallucinations involve sensory perceptions of taste. Olfactory hallucinations involve sensory perceptions of smell. Visceral hallucinations involve sensory perceptions of sensation.
Question 3 of 5
A client is admitted to the labor room. She is dilated 4 cm. She is placed on electric fetal monitoring. Which of the following observations necessitates notifying the physician?
Correct Answer: A
Rationale: These are tetanic in nature and can cause rupture of the uterus. The FHR decreases during contractions owing to vasoconstriction and should recover after the contraction. Beat-to-beat variability is a normal finding and demonstrates fetal well-being. The FHR may decrease at the beginning of a contraction owing to head compression.
Question 4 of 5
A 71-year-old client fell and injured her left leg while cooking in the kitchen. Her husband calls the ambulance, and she is taken to the emergency department at a local hospital. X-ray reports confirm that she has an intertrochanteric fracture of the left femur. Her left leg will require skeletal traction initially and then surgery. The nurse knows that this type of traction will be used:
Correct Answer: A
Rationale: Skeletal traction is the application of traction directly to bone with the use of pins and wires or tongs for the purpose of providing a strong, steady, continuous longitudinal pull on the bone. It is indicated for preoperative immobilization and positioning of hip and femur fractures. A type of skeletal traction (balanced suspension with a Thomas splint and Pearson attachment) uses a sling to support the extremity, but it also uses weights to provide a strong, steady continuous pull on the extremity. A sling is used instead of pins. Pelvic traction provides an intermittent pull over the pelvis and bone, whereas skeletal traction is continuous. Pelvic traction does not use pins. Skeletal traction uses weights at the end of the bed to provide a continuous pull on long bones. Weights are not applied to both ends of the bed.
Question 5 of 5
Stat serum electrolytes ordered for a client in acute renal failure revealed a serum potassium level of 6.4. The physician is immediately notified and orders 50 mL of dextrose and 10 U of regular insulin IV push. The nurse administering these drugs knows the rationale for this therapy is to:
Correct Answer: D
Rationale: Sodium polystyrene sulfonate (Kayexalate), a cation exchange resin, exchanges sodium ions for potassium ions in the large intestine reducing the serum potassium. Calcium is administered to protect the myocardium from the adverse effects of hyperkalemia. Serum levels reflect hyperkalemia. Rapid catabolism releases potassium from the body tissue into the bloodstream. Infection and hyperthermia increase the process of catabolism. The administration of dextrose and regular insulin IV forces potassium back into the cells decreasing the potassium in the serum.
