NCLEX RN Predictor Exam - Nurselytic

Correct Answer: A

Rationale: Specific gravity in urinalysis measures the concentration of solutes in urine compared to that of distilled water. This comparison helps in assessing the kidney's ability to concentrate urine properly. It is a valuable test even in dehydrated patients as it provides insights into renal function. Specific gravity can be measured using various methods, including a refractometer or reagent strips. Normal specific gravity readings of human urine typically range from 1.005 to 1.030.
Choice A is correct as it accurately describes the purpose of specific gravity in urinalysis.

Choices B and C are incorrect as specific gravity remains relevant in dehydrated patients and can be measured using different techniques, not solely a refractometer.

Correct Answer: D

Rationale: Efforts to reduce hospital-acquired infections (HAIs) involve being aware that the Joint Commission considers death or serious injury resulting from HAIs a sentinel event, which must be reported. While more than 20 states require reporting of HAI rates to the CDC, it is not a nationwide CDC requirement. The gastrointestinal tract is not a specific common site for HAIs; rather, bacteria are the primary cause. Ensuring restraints are properly secured is important for patient safety but not directly related to reducing HAIs.

Correct Answer: A

Rationale: Goggles may be reused unless they are overly contaminated by material that has splashed in the nurse's face and cannot be effectively rinsed off. Gowns are at high risk for contamination and should be used only once and then discarded or washed. Surgical masks and gloves should never be washed or reused. Goggles provide eye protection from splashes and should be cleaned and disinfected after each use to ensure proper protection.

Correct Answer: D

Rationale: The correct answer is 'All patients receiving care in hospitals.' Standard precautions apply to all patients in healthcare settings, regardless of their infection status. These recommendations include all body fluids except sweat, non-intact skin, and mucous membranes.
Choice A is incorrect as standard precautions are not limited to patients with diagnosed infections.
Choice B is incorrect as standard precautions extend beyond blood or body fluids with visible blood.
Choice C is incorrect as sweat is an exception to the body fluids covered under standard precautions.

Correct Answer: D

Rationale: Option D is the most appropriate safety measure in this scenario. Using a bed exit safety monitoring device allows the client to retain some independence while ensuring that the nursing staff is alerted when assistance is needed. This solution promotes client safety without compromising their autonomy. Option A, restraining the client in bed, can lead to increased agitation, confusion, and a loss of independence. Option B, asking a family member to stay with the client, shifts the responsibility away from the healthcare team. Option C, checking the client every 15 minutes, is not a sufficient safety measure as the client could attempt to get out of bed in the unobserved interval, risking falls and injury.
