Nursing Elites

1. Patients exhibiting signs of cyanosis will:

• A. show signs of hyperoxia.
• B. have increased O2 saturation.
• C. have blood levels of CO2 higher than O2 levels.
• D. None of the above.

Correct answer: C

Rationale: Cyanosis is a bluish discoloration of the skin and mucous membranes resulting from low blood oxygen levels. When a patient exhibits cyanosis, it indicates that their blood is poorly oxygenated, leading to a higher concentration of CO2 compared to oxygen. Options A and B are incorrect as cyanosis is associated with low oxygen levels, not hyperoxia or increased O2 saturation. Therefore, the correct answer is that patients exhibiting cyanosis will have blood levels of CO2 higher than O2 levels.

2. 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.

3. Which of the following lists the recommended sequence for removing soiled personal protective equipment when preparing to leave a patient's room?

• A. Gown, goggles, mask, gloves, and exit the room.
• B. Gloves, wash hands, remove gown, mask, and goggles.
• C. Gloves, goggles, gown, mask, and wash hands.
• D. Gloves, goggles, gown, mask, and wash hands.

Correct answer: D

Rationale: The correct sequence for removing soiled personal protective equipment is crucial to prevent contamination. Gloves should always be removed first as they are most likely to be contaminated. Following the removal of gloves, goggles, gown, mask, and finally washing hands is recommended. Choice A is incorrect as gloves should be removed first. Choice B is incorrect as the sequence is not in the recommended order. Choice D is incorrect as gloves should be removed before goggles.

4. Which of these actions illustrates the correct technique for a nurse when assessing oral temperature with a glass thermometer?

• A. Wait 30 minutes if the patient has ingested hot or iced liquids.
• B. Leave the thermometer in place for 3 to 4 minutes if the patient is afebrile.
• C. Shake the glass thermometer down to 35.5�C before taking the patient's temperature.
• D. Place the thermometer at the base of the tongue and ask the patient to close his or her lips.

Correct answer: B

Rationale: The correct technique for assessing oral temperature with a glass thermometer involves leaving the thermometer in place for 3 to 4 minutes if the patient is afebrile and up to 8 minutes if the patient is febrile. Waiting 30 minutes if the patient has ingested hot or iced liquids is incorrect; instead, the nurse should wait 15 minutes in such cases. Shaking the glass thermometer down to 35.5�C, not 37.5�C, is the correct procedure before taking the patient's temperature. Placing the thermometer at the base of the tongue, not the front, and asking the patient to close their lips is the proper way to position the thermometer. Therefore, the correct answer is to leave the thermometer in place for 3 to 4 minutes if the patient is afebrile and up to 8 minutes if the patient is febrile.

5. While caring for Mr. Charles Y., you see a notation on the nursing care plan that states, 'remind the patient to use the incentive spirometer tid.' This patient will be reminded at which of the following times?

• A. 10:00 AM
• B. 10 am and 2 pm
• C. 10 am, 2 pm, and 6 pm
• D. 10 am, 2 pm, 6 pm, and 10 pm

Correct answer: C

Rationale: The abbreviation 'tid' stands for 'ter in die,' which means three times a day. In this case, the patient should be reminded to use the incentive spirometer at 10 am, 2 pm, and 6 pm. Option A, '10 am,' is too infrequent for tid dosing. Option B, '10 am and 2 pm,' is missing the third reminder at 6 pm. Option D, '10 am, 2 pm, 6 pm, and 10 pm,' includes an additional time that is not part of the standard tid dosing schedule.
