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. The healthcare professional is preparing to measure the length, weight, chest, and head circumference of a 6-month-old infant. Which measurement technique is correct?

• A. Measuring the infant's length using a tape measure
• B. Weighing the infant on an electronic standing scale
• C. Measuring the chest circumference at the nipple line with a tape measure
• D. Measuring the head circumference by wrapping the tape measure around the head

Correct answer: C

Rationale: For accurate measurements, specific techniques are required for different parameters in infants. Measuring the chest circumference involves encircling the chest at the nipple line. Length should be measured on a horizontal measuring board. Weight should be measured using a platform-type balance scale. Head circumference measurement entails ensuring the tape is aligned at the eyebrows and prominent frontal and occipital bones for the widest span. Therefore, the correct technique for measuring the chest circumference is at the nipple line with a tape measure. The other options are incorrect because length should be measured on a horizontal board, weight should be measured on a balance scale, and head circumference should be measured around the head, not over the nose and cheekbones.

3. When performing CPR, at what rate should chest compressions be applied?

• A. 100 per minute
• B. 60 per minute
• C. As quickly as possible
• D. 200 per minute

Correct answer: A

Rationale: During CPR, chest compressions should be applied at a rate of 100 compressions per minute in order to effectively circulate blood and oxygen to vital organs. Option A, '100 per minute,' is the correct answer as it aligns with the recommended compression rate in CPR guidelines. Option B, '60 per minute,' is incorrect as it is too slow and may not provide adequate circulation. Option C, 'As quickly as possible,' is vague and does not specify the recommended compression rate. Option D, '200 per minute,' is incorrect as it exceeds the recommended rate and may not be as effective in maintaining perfusion.

4. The nurse is assessing children in a pediatric clinic. Which statement is true regarding the measurement of blood pressure in children?

• A. Blood pressure guidelines for children are based on age.
• B. Phase II Korotkoff sounds are the best indicator of systolic blood pressure in children.
• C. Using a Doppler device is recommended for accurate blood pressure measurements until adolescence.
• D. The disappearance of phase V Korotkoff sounds can be used for the diastolic reading in children.

Correct answer: D

Rationale: The disappearance of phase V Korotkoff sounds can be used for the diastolic reading in children, as well as in adults. Blood pressure guidelines for children are based on more than just age, but also sex and height. Phase I Korotkoff, not Phase II, is the best indicator of systolic blood pressure. The true statement regarding the measurement of blood pressure in children is that the disappearance of phase V Korotkoff sounds can be used for the diastolic reading in children, as well as in adults.

5. On admission to the psychiatric unit, the client is trembling and appears fearful. The nurse's initial response should be to:

• A. Give the client orientation materials and review the unit rules and regulations.
• B. Introduce him/her and accompany the client to the client's room.
• C. Take the client to the day room and introduce him/her to the other clients.
• D. Ask the nursing assistant to get the client's vital signs and complete the admission search.

Correct answer: B

Rationale: Anxiety is triggered by change that threatens the individual's sense of security. In response to anxiety in clients, the nurse should remain calm, minimize stimuli, and move the client to a calmer, more secure/safe setting. The correct initial response is to introduce the client and accompany them to their room. This approach helps the client feel oriented, safe, and supported. Giving orientation materials or reviewing rules and regulations may overwhelm the client further. Taking the client to the day room and introducing them to other clients could increase anxiety by exposing them to unfamiliar faces. Asking the nursing assistant to get vital signs and complete admission tasks can wait until the client feels more settled and secure in their environment.
