Nursing Elites

1. A leukemia patient has a relative who wants to donate blood for transfusion. Which of the following donor medical conditions would prevent this?

• A. A history of hepatitis C five years previously
• B. Cholecystitis requiring cholecystectomy one year previously
• C. Asymptomatic diverticulosis
• D. Crohn's disease in remission

Correct answer: A

Rationale: A history of hepatitis C five years previously would prevent a donor from donating blood for transfusion. Hepatitis C is a viral infection transmitted through bodily fluids, such as blood, causing inflammation of the liver. Patients with hepatitis C may not donate blood for transfusion due to the high risk of infection in the recipient. Cholecystitis requiring cholecystectomy one year previously, asymptomatic diverticulosis, and Crohn's disease in remission are not contraindications for blood donation as they do not pose a risk of transmitting infections to the recipient.

2. A client has applied a cold pack to their arm to help decrease swelling and inflammation after an injury. Which of the following signs indicates that the cold pack should be removed?

• A. The skin on the arm appears mottled
• B. The cold pack has been in place for 10 minutes
• C. The client complains of feeling nauseated
• D. The capillary refill in the area distal to the arm is 2 seconds

Correct answer: A

Rationale: When using a cold pack for therapeutic purposes, it is essential to monitor the site to prevent tissue damage. Prolonged use of cold therapy can lead to pale, mottled skin with a bluish appearance. This change in skin color indicates poor circulation, and the cold pack should be removed immediately to prevent tissue injury. Choices B, C, and D are incorrect because the duration of cold pack application, client complaints of nausea, and capillary refill time do not specifically indicate the need for the cold pack to be removed due to potential tissue damage.

3. 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.

4. Which of the following is part of client teaching regarding antiembolism stockings?

• A. Instruct the client to roll the top portion of the stocking down if it is too long
• B. Stockings are applied with the toes uncovered at the end
• C. Measure for thigh-high stockings from the foot to the knee
• D. Stockings are to be smooth from end to end without wrinkles

Correct answer: D

Rationale: When educating clients about antiembolism stockings, it is essential to emphasize that the stockings should be smooth from end to end without wrinkles. Wrinkles in the stockings can impede circulation, defeating the purpose of wearing them to prevent blood clot formation. Instructing the client to roll the top portion of the stocking down if it is too long (Choice A) is incorrect as it can create unnecessary pressure points. Stockings should be applied with the toes covered at the end (Choice B) to ensure proper compression. Measuring for thigh-high stockings should be done from the knee to the foot (Choice C) to ensure the correct fit and compression gradient.

5. The healthcare provider is examining a patient who is reporting "feeling cold."? Which is a mechanism of heat loss in the body?

• A. Exercise
• B. Radiation
• C. Metabolism
• D. Food digestion

Correct answer: B

Rationale: When the body needs to lose heat, one of the mechanisms it employs is radiation. Radiation involves the transfer of heat from the body to the environment in the form of infrared waves. While metabolism, exercise, and food digestion contribute to heat production, they are not mechanisms for heat loss. Metabolism generates heat as a byproduct, exercise increases metabolic rate leading to heat production, and food digestion involves some heat generation, but these processes do not directly facilitate heat loss. Therefore, in the scenario where the patient is feeling cold, radiation is the primary mechanism for the body to lose excess heat and maintain a stable internal temperature.
