1. Specific gravity in urinalysis:

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. When are manual hematocrits done?

Correct answer: All of the above.

Rationale: Manual hematocrits are performed to monitor anemia, which involves measuring the percentage of red blood cells in the blood. The process involves collecting blood in a microhematocrit tube, then centrifuging it to separate the plasma from the cells. By measuring the ratio of plasma to cells, healthcare providers can assess the patient's hematocrit level. Therefore, all the provided options are correct as they collectively describe the purpose and procedure of manual hematocrits.

3. Why should a palpated pressure be performed before auscultating blood pressure?

Correct answer: To detect the presence of an auscultatory gap.

Rationale: Performing a palpated pressure before auscultating blood pressure helps in detecting the presence of an auscultatory gap. An auscultatory gap is a period during blood pressure measurement when Korotkoff sounds temporarily disappear before reappearing. Inflation of the cuff 20 to 30 mm Hg beyond the point where a palpated pulse disappears helps in identifying this gap. This technique ensures accurate blood pressure measurement by preventing the underestimation of blood pressure values. The other options are incorrect because palpating the pressure is not primarily done to hear Korotkoff sounds more clearly, avoid missing falsely elevated blood pressure, or readily identify a specific phase of Korotkoff sounds.

4. A 28-year-old male has been found wandering around in a confusing pattern. The male is sweaty and pale. Which of the following tests is most likely to be performed first?

Correct answer: Blood sugar check

Rationale: In a 28-year-old male presenting with confusion, sweating, and pallor, the most likely cause is hypoglycemia, especially with no mention of trauma or infection. Therefore, the initial test to be performed should be a blood sugar check to rule out low blood sugar levels. Checking blood sugar levels is crucial in such a scenario as hypoglycemia can lead to altered mental status. A CT scan (choice B) is not typically the initial test for altered mental status without any focal neurological signs or head trauma. Blood cultures (choice C) are more relevant in cases suspected of infection, which is not a primary concern in this scenario. Arterial blood gases (choice D) may be considered later if there are concerns about respiratory status or acid-base disturbances, but in this case, checking the blood sugar level is the most immediate and appropriate action.

5. Which of the following clients is most likely ready to be dismissed from an inpatient care setting to home?

Correct answer: A 4-year old male with an oxygen saturation of 96% on room air

Rationale: Clients must meet a certain amount of set criteria before they will be discharged from a healthcare facility. Although guidelines may vary between locations, most healthcare facilities expect clients to have adequate oxygenation, nutrition, and elimination; and be free from fever, vomiting, and significant pain
