Nursing Elites

1. To which of the following do the CDC Standard precautions recommendations apply?

• A. Patients with diagnosed infections only
• B. Blood or body fluids with visible blood only
• C. All body fluids including sweat
• D. All patients receiving care in hospitals

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.

2. Which of these specific measurements is the best index of a child's general health?

• A. Body mass index
• B. Height and weight
• C. Head circumference
• D. Chest circumference

Correct answer: B

Rationale: Height and weight are the most accurate measurements to assess a child's general health. These measurements reflect the physical growth and development of the child, indicating overall health status. Choices C and D, head circumference and chest circumference, are important measurements for specific assessments but do not provide as comprehensive an overview of general health as height and weight. Body mass index (BMI) is a calculation based on height and weight, making height and weight more direct and primary indicators of a child's health compared to BMI.

3. Which bloodborne pathogen is the most virulent? (Choose the BEST answer.)

• A. HCV
• B. HPV
• C. HIV
• D. HBV

Correct answer: A

Rationale: The correct answer is HCV (Hepatitis C Virus). Hepatitis C is considered the most virulent bloodborne pathogen, being 100 times more virulent than Hepatitis B. HPV (Human Papillomavirus) is a sexually transmitted infection but is not a bloodborne pathogen. HIV (Human Immunodeficiency Virus) affects the immune system but is not as virulent as Hepatitis C in terms of bloodborne transmission. HBV (Hepatitis B Virus) is less virulent compared to HCV in the context of bloodborne transmission.

4. The student observes a patient with no breathing problems. Which action by the student indicates a need to review respiratory assessment skills?

• A. The student starts at the apices of the lungs and moves to the bases.
• B. The student compares breath sounds from side to side, avoiding bony areas.
• C. The student places the stethoscope over the posterior chest and listens during expiration.
• D. The student instructs the patient to breathe slowly and a little more deeply than normal through the mouth.

Correct answer: C

Rationale: The correct answer is C. Listening only during inspiration instead of both inspiration and expiration indicates a need for a review of respiratory assessment skills. During chest auscultation, it is essential to listen to at least one cycle of inspiration and expiration at each placement of the stethoscope. Instructing the patient to breathe slowly and a little deeper than normal through the mouth is a correct practice during auscultation. The correct sequence for lung auscultation is from the apices to the bases, comparing breath sounds bilaterally, avoiding bony areas. It is crucial to place the stethoscope over lung tissue rather than bony prominences to accurately assess lung sounds.

5. A patient's blood pressure is 118/82 mm Hg. The patient asks the nurse, "What do the numbers mean?"? Which is the best reply by the nurse?

• A. "The numbers are within the normal range and are nothing to worry about."?
• B. "The bottom number is the diastolic pressure and reflects the pressure in the arteries when the heart relaxes."?
• C. "The top number is the systolic blood pressure and reflects the pressure of the blood against the arteries when the heart contracts."?
• D. "The concept of blood pressure can be complex. The primary thing to be concerned about is the top number, or the systolic blood pressure."?

Correct answer: C

Rationale: The systolic pressure is the maximum pressure felt on the artery during left ventricular contraction, or systole. The diastolic pressure is the elastic recoil, or resting, pressure that the blood constantly exerts in between each contraction. The nurse should answer the patient's question in terms they can understand and not just say it is normal and there is nothing to worry about. The diastolic pressure is the pressure in the vessels when the heart is at rest, not the stroke volume. Both the systolic and diastolic blood pressure are important. Choice A is incorrect as providing a vague reassurance does not address the patient's query. Choice B is incorrect as it inaccurately describes the diastolic pressure as reflecting stroke volume, which is incorrect. Choice D is incorrect as it oversimplifies the explanation, focusing solely on the top number without providing a complete understanding of blood pressure.
