Extract:
Question 1 of 5
A nurse is caring for a client who has a diagnosis of alcohol withdrawal. Which serum laboratory value validates the client's admitting diagnosis? A serum:
Correct Answer: A
Rationale: Low magnesium (1.8 mEq/L below normal 1.8-2.5 mEq/L) is associated with alcohol withdrawal contributing to symptoms like tremors and seizures due to hypomagnesemia from poor nutrition and alcohol’s diuretic effect. Normal potassium (3.5-5.0 mEq/L) calcium (8.5-10.2 mg/dL) and phosphorus (2.5-4.5 mg/dL) levels do not specifically validate alcohol withdrawal.
Question 2 of 5
The nurse is caring for a client who is at high risk for development of pressure injury. The client is able to move independently but has been placed on bedrest. The client has experienced two episodes of urinary incontinence. Which intervention(s) should the nurse include in the care plan?
Correct Answer: A,D,E
Rationale: Shifting weight every 15 minutes reduces pressure on bony prominences moisture barrier cream protects against incontinence-related skin breakdown and a specialty mattress distributes pressure to prevent ulcers. Raising the bed at 45 degrees increases shear and massaging prominences risks tissue damage.
Question 3 of 5
Which nursing action is most helpful in thinning a client's thick respiratory secretions?
Correct Answer: D
Rationale: Adequate fluid intake thins respiratory secretions by promoting hydration and mobilizing mucus reducing viscosity and aiding expectoration. Oxygen therapy supports oxygenation but not secretion thinning consistent air temperature has minimal impact and supine positioning may worsen secretion clearance by promoting stasis.
Question 4 of 5
The nurse is aware that a common cause of under delegation in client care is:
Correct Answer: C
Rationale: Under-delegation often stems from a nurse’s need for perfectionism and control leading to reluctance to delegate tasks as they fear tasks won’t meet their standards. Over-delegation to assistive personnel is related to excessive delegation not under-delegation. A high degree of trust would facilitate delegation and nurses’ heavy workloads mean they often lack time to do all tasks themselves contradicting the idea of having time as a cause.
Question 5 of 5
It is most critical for the nurse to use a filtered needle when preparing a parenteral medication that:
Correct Answer: A
Rationale: A filtered needle prevents glass particles from an ampule (broken to access medication) entering the syringe reducing risks of tissue damage or embolism. Mixing medications reconstitution or clear solutions do not inherently produce particles requiring filtration.
