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. Which is the most effective action for controlling the spread of infection?

• A. Thorough hand hygiene
• B. Wearing gloves and masks when providing direct client care
• C. Implementing appropriate isolation precautions
• D. Administering broad-spectrum prophylactic antibiotics

Correct answer: A

Rationale: Thorough hand hygiene is the most effective action for controlling the spread of infection as hands are a common source of transmission. Regular and routine hand hygiene helps prevent the movement of potentially infective materials. Wearing gloves and masks is important when providing direct client care to protect both the caregiver and the patient, but it is not as effective as thorough hand hygiene in preventing overall infection spread. Implementing appropriate isolation precautions is necessary for clients with known communicable diseases, but it is not as universally effective in preventing the spread of various infections. Administering broad-spectrum prophylactic antibiotics is not an appropriate measure for controlling the spread of infection as routine use can lead to superinfection and the development of resistant organisms.

3. During a class on cultural practices, the nurse hears the term cultural taboo. Which statement illustrates the concept of a cultural taboo?

• A. Trying prayer before seeking medical help
• B. Believing that illness is a punishment of sin
• C. Refusing to accept blood products as part of treatment
• D. Stating that a child's birth defect is the result of the parents' sins

Correct answer: C

Rationale: The concept of a cultural taboo involves practices that are forbidden or avoided within a particular culture. Refusing to accept blood products as part of treatment is a clear example of a cultural taboo, as some cultures or religions prohibit the use of blood products for medical purposes. This practice is deeply rooted in cultural beliefs and traditions. The other choices provided do not directly relate to cultural taboos. Trying prayer before seeking medical help, believing illness is a punishment of sin, and stating that a child's birth defect is the result of parents' sins are beliefs or actions based on religious or personal beliefs, but they do not specifically represent cultural taboos.

4. Which of the following is a negative outcome associated with impaired mobility?

• A. Increased amounts of calcium are absorbed from circulation
• B. A drop in blood pressure occurs when rising from a sitting to a standing position
• C. The amount of mucus in the bronchi and lungs decreases
• D. The vessel walls of the circulatory system thicken

Correct answer: B

Rationale: A client with impaired mobility may develop changes in body systems that put them at risk of further illness or injury. One negative outcome associated with impaired mobility is orthostatic hypotension, where blood pressure drops significantly when moving from a sitting or lying position to a standing position. This drop in blood pressure can lead to symptoms such as dizziness or fainting. This occurs because blood circulates more slowly or pools in the distal extremities due to impaired mobility. Choice A is incorrect because increased calcium absorption is not a typical negative outcome associated with impaired mobility. Choice C is incorrect because a decrease in mucus in the bronchi and lungs is not a common negative outcome of impaired mobility. Choice D is incorrect because thickening of vessel walls in the circulatory system is not directly associated with impaired mobility.

5. During an examination, a nurse notices a draining ulceration on a patient's lower leg. What is the most appropriate action in this situation?

• A. Wash hands and then contact the physician.
• B. Continue to examine the ulceration and then wash hands.
• C. Wash hands, put on gloves, and continue with the examination of the ulceration.
• D. Wash hands, proceed with the rest of the physical examination, and perform the examination of the leg ulceration last.

Correct answer: C

Rationale: In this scenario, the most appropriate action is to wash hands, put on gloves, and then continue examining the ulceration. Wearing gloves is crucial when there is a possibility of contact with body fluids, as in the case of a draining ulceration. Contacting the physician is not necessary at this point; the immediate focus should be on proper infection control by washing hands and wearing gloves. Changing the order of the examination is not recommended as it is important to follow a systematic approach to avoid missing any crucial assessments.
