Nursing Elites

1. When considering the concepts related to blood pressure, which statement best describes the concept of mean arterial pressure (MAP)?

• A. MAP is the pressure of the arterial pulse.
• B. MAP reflects the stroke volume of the heart.
• C. MAP is the pressure forcing blood into the tissues, averaged over the cardiac cycle.
• D. MAP is an average of the systolic and diastolic blood pressures and reflects tissue perfusion.

Correct answer: C

Rationale: Mean Arterial Pressure (MAP) is the pressure that forces blood into the tissues, averaged over the cardiac cycle. It is not the pressure of the arterial pulse (Choice A), nor does it directly reflect the stroke volume of the heart (Choice B). While MAP involves systolic and diastolic pressures, it is not simply an average of these two values as diastole lasts longer. Instead, MAP is closer to diastolic pressure plus one third of the pulse pressure. The best description of MAP is that it represents the pressure forcing blood into the tissues, averaged over the cardiac cycle.

2. Your patient who had AIDS/HIV has just died. Should you still use standard precautions as you provide post-mortem care?

• A. Yes, because the virus is still transmissible
• B. Yes, because respect must still be maintained
• C. No, because the virus is no longer transmissible
• D. No, because it is disrespectful

Correct answer: A

Rationale: Yes, you should still use standard precautions even after an HIV/AIDS patient has died. The virus can remain infectious after death, and healthcare workers need to protect themselves from potential exposure. Choice B is incorrect because while respect is important, the primary reason for using standard precautions is to prevent transmission of infectious diseases. Choice C is incorrect as the virus can still be transmissible even after the patient's death. Choice D is incorrect as using standard precautions is a matter of infection control, not a question of respect.

3. What is the minimum amount of personal protective equipment for a nurse when working with a newborn immediately after a high-risk delivery in a client's room?

• A. Sterile gown, gloves
• B. Mask, gown, shoe covers
• C. Gloves
• D. Hat, mask, gloves, gown, shoe covers

Correct answer: C

Rationale: The correct answer is gloves. When attending a high-risk delivery and handling a newborn immediately after birth, the minimum personal protective equipment required for a nurse includes gloves. This is essential to protect the nurse from potential exposure to the mother's blood or body fluids that may be present on the newborn's skin. Choices A, B, and D include additional protective equipment that is not necessary for this specific scenario. Wearing gloves is crucial for infection control and to prevent the transmission of pathogens.

4. While percussing over the liver of a patient, the nurse notices a dull sound. What should the nurse do?

• A. Consider this a normal finding
• B. Palpate this area for an underlying mass
• C. Reposition the hands and attempt to percuss in this area again
• D. Consider this finding as abnormal and refer the patient for additional treatment

Correct answer: A

Rationale: When percussing over relatively dense organs, such as the liver or spleen, a dull sound is a normal finding due to the organ's density. This occurs because the sound waves produced by tapping on the organ travel through the dense tissue, resulting in a dull sound. Therefore, the correct action for the nurse in this scenario is to consider a dull sound over the liver as a normal finding. Palpating for an underlying mass (Choice B) is not indicated based on the percussion finding alone. Repositioning the hands and repeating the percussion (Choice C) may not change the dull sound over the liver. Referring the patient for additional treatment (Choice D) without understanding the normal percussion findings over the liver would be premature. Thus, the most appropriate action is to interpret the dull sound as a normal finding.

5. When should you wear gloves?

• A. preparing infant formula for a newborn baby
• B. transferring breast milk into a baby bottle
• C. knocking on a patient's door
• D. opening a patient's door

Correct answer: B

Rationale: You must wear gloves when transferring breast milk into a baby bottle because breast milk is considered a bodily fluid. It is essential to avoid direct contact to prevent contamination. When preparing infant formula, gloves are not required as formula is not a bodily fluid. Knocking on or opening a patient's door does not involve direct contact with bodily fluids, so gloves are unnecessary in those situations.
