Nursing Elites

1. Specific gravity in urinalysis:

• A. compares the concentration of urine to that of distilled water
• B. is useless when the patient is dehydrated
• C. can only be measured using a refractometer
• D. None of the above

Correct answer: compares the concentration of urine to that of distilled water

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.

2. The healthcare provider is reviewing theories of illness. The germ theory, which states that microscopic organisms such as bacteria and viruses are responsible for specific disease conditions, is a basic belief of which theory of illness?

• A. Holistic
• B. Biomedical
• C. Naturalistic
• D. Magicoreligious

Correct answer: Biomedical

Rationale: The correct answer is B: Biomedical. Among the biomedical explanations for disease is the germ theory, which states that microscopic organisms such as bacteria and viruses are responsible for specific disease conditions. The naturalistic or holistic perspective holds that the forces of nature must be kept in natural balance. The magicoreligious perspective holds that supernatural forces dominate and cause illness or health. Therefore, options A, C, and D are incorrect as they do not align with the germ theory explanation provided in the question.

3. Which of the following interventions is most appropriate for a client with a diagnosis of Risk for Activity Intolerance?

• A. Perform nursing activities throughout the entire shift
• B. Assess for signs of increased muscle tone
• C. Minimize environmental noise
• D. Teach clients to perform the Valsalva maneuver

Correct answer: C: Minimize environmental noise

Rationale: The most appropriate intervention for a client diagnosed with Risk for Activity Intolerance is to minimize environmental noise. Environmental noise can increase the energy demand on the client as they try to manage their responses to stimuli. By reducing excess noise, the nurse helps promote rest and conserves the client's energy, which is crucial in managing activity intolerance. Choice A is incorrect because increasing nursing activities may exacerbate the client's intolerance to activity. Choice B is incorrect as assessing for signs of increased muscle tone does not directly address the issue of activity intolerance. Choice D is incorrect as teaching the Valsalva maneuver is not relevant to managing activity intolerance in this scenario.

4. What is the initial step to take when a patient passes out at the front desk?

• A. Call 911.
• B. Initiate CPR.
• C. Shake the patient and ask if they are okay.
• D. Check for a pulse.

Correct answer: Shake the patient and ask if they are okay.

Rationale: The correct initial step when a patient passes out at the front desk is to shake the patient gently and ask if they are okay. This step aims to assess the patient's level of responsiveness. Checking for a pulse or initiating CPR should only be done if the patient does not respond to being shaken. Calling 911 can be the next step after assessing the patient's immediate condition and providing necessary assistance.

5. The nurse informs the physical therapy department that the client is too weak to use a walker and needs to be transported by wheelchair. Which step of the nursing process is the nurse engaged in at this time?

• A. Assessment
• B. Planning
• C. Implementation
• D. Evaluation

Correct answer: Implementation

Rationale: The nurse is responsible for coordinating the plan of care with other disciplines to ensure the client's safety. This action represents the implementation phase of the nursing process. During the implementation phase, the nurse puts the care plan into action, which includes coordinating with other healthcare team members like the physical therapy department. Assessment involves data gathering, planning involves goal setting, and evaluation involves determining the attainment of client goals.
