1. Which of the following is classified as a prerenal condition that affects urinary elimination?

• A. Nephrotoxic medications
• B. Pericardial tamponade
• C. Neurogenic bladder
• D. Polycystic kidney disease

Correct answer: B

Rationale: A prerenal condition is one that causes reduced urinary elimination by affecting the blood flow to the kidneys. Pericardial tamponade is a condition that impacts the heart's ability to pump sufficient blood, leading to decreased blood flow to vital organs such as the kidneys. This reduction in blood flow to the kidneys can result in decreased urine production. The other choices, such as nephrotoxic medications, neurogenic bladder, and polycystic kidney disease, do not primarily affect the blood flow to the kidneys and are not classified as prerenal conditions that impact urinary elimination.

2. A patient's urine specimen tested positive for bilirubin. Which of the following is most true?

• A. The patient should be evaluated for kidney disease
• B. The specimen was probably left at room temperature for more than two hours
• C. The specimen is positive for bacteria
• D. The specimen should be stored in an area protected from light

Correct answer: D

Rationale: Bilirubin is easily broken down by light, so all samples testing positive for bilirubin should be protected from light exposure. Storing the specimen in an area protected from light helps maintain the integrity of the bilirubin levels for accurate testing. Choice A is incorrect because the presence of bilirubin in urine does not necessarily indicate kidney disease. Choice B is incorrect as the exposure to light, not room temperature, affects bilirubin levels. Choice C is incorrect as the presence of bilirubin does not indicate the presence of bacteria in the specimen.

3. The nurse is discussing the term subculture with a student nurse. Which statement by the nurse would best describe subculture?

• A. "Fitting as many people as possible into the majority culture."?
• B. "Identifying small groups of people who do not want to be identified with the larger culture."?
• C. "Singling out groups of people who suffer differential and unequal treatment as a result of cultural variations."?
• D. "Recognizing groups of people within a culture with shared characteristics that are not common to all members of the culture."?

Correct answer: D

Rationale: A subculture refers to a group of people within a larger culture who share distinct beliefs, values, or attitudes that are not universal among all members of the larger culture. Subcultures can emerge based on factors such as ethnicity, religion, education, occupation, age, and gender. The correct answer describes the concept of a subculture accurately. Choices A, B, and C are incorrect because they do not capture the essence of a subculture. Fitting people into the majority culture, identifying small groups who distance themselves from the larger culture, or singling out individuals facing differential treatment do not define subculture. Subcultures represent specific groups with shared characteristics that differentiate them from the broader cultural norms.

4. While auscultating heart sounds, the nurse hears a murmur. Which of these instruments would be used to assess this murmur?

• A. Electrocardiogram
• B. Bell of the stethoscope
• C. Diaphragm of the stethoscope
• D. Palpation with the nurse's palm of the hand

Correct answer: B

Rationale: The correct instrument to assess a murmur while auscultating heart sounds is the bell of the stethoscope. An electrocardiogram is used to measure the heart's electrical activity, not to assess murmurs. Palpation with the nurse's palm of the hand is a method to assess pulses or textures, not heart murmurs. The diaphragm of the stethoscope is typically used for high-pitched sounds like breath, bowel, and normal heart sounds, whereas the bell is more suitable for soft, low-pitched sounds such as murmurs or extra heart sounds.

5. In the Gram Stain procedure, which component acts as the mordant?

• A. Crystal violet
• B. Methyl alcohol
• C. Iodine
• D. Safranin

Correct answer: C

Rationale: In the Gram Stain procedure, the mordant is Gram's Iodine. The purpose of the mordant is to form a complex with the crystal violet, enhancing its ability to bind to the cell wall. Crystal violet is actually the primary stain used in the Gram Stain procedure to initially color all cells. Methyl alcohol is the decolorizer that removes the crystal violet from certain cell types. Safranin is the counterstain used to stain those cells that did not retain the crystal violet stain after the decolorization step.
