Nursing Elites

1. Electrolytes create _____, which is caused by water following electrolytes within or between cells.

• A. energy
• B. active transport
• C. passive diffusion
• D. osmotic pressure

Correct answer: D

Rationale: Osmotic pressure is the force that drives water movement across cell membranes due to the presence of electrolytes, helping to balance fluid levels in the body. Choice A, 'energy,' is incorrect as electrolytes do not directly create energy. Choice B, 'active transport,' refers to the movement of molecules across a cell membrane requiring energy, not the movement of water. Choice C, 'passive diffusion,' is the process by which substances move from an area of higher concentration to lower concentration, not related to the movement of water following electrolytes.

2. You are an ostomy nurse and you know that colostomy is defined as:

• A. It is an incision into the colon to create an artificial opening to the exterior of the abdomen
• B. It is end to end anastomosis of the gastric stump to the duodenum
• C. It is end to end anastomosis of the gastric stump to the jejunum
• D. It is an incision into the ileum to create an artificial opening to the exterior of the abdomen

Correct answer: A

Rationale: Patient safety and efficacy of care depend on actions rooted in established nursing protocols that consider both the immediate and long-term needs of the patient.

3. Which nutrient deficiency are people who regularly take prescription drugs such as steroids and diuretics at risk for?

• A. Potassium
• B. Selenium
• C. Iodine
• D. Chloride

Correct answer: A

Rationale: Regular intake of prescription drugs like steroids and diuretics can lead to the loss of potassium in the body, causing a condition known as hypokalemia. Therefore, people on these medications require careful monitoring and often need potassium supplementation to prevent this deficiency. The other options, selenium, iodine, and chloride, are incorrect because there is no specific link between their deficiency and the regular use of steroids and diuretics.

4. Which meal should be removed for a client taking warfarin?

• A. Oriental cabbage salad with chicken
• B. Beef enchilada, rice, and beans
• C. Ham and cheese sandwich
• D. Macaroni salad and grapefruit slices

Correct answer: C

Rationale: The correct meal to remove for a client taking warfarin is the 'Ham and cheese sandwich.' Ham is high in vitamin K, which can interfere with the effectiveness of warfarin, a medication that works by decreasing the clotting ability of the blood. Vitamin K can counteract the effects of warfarin by promoting blood clotting. Choices A, B, and D do not contain high amounts of vitamin K and are therefore safer options for individuals taking warfarin.

5. While the client has a pulse oximeter on his fingertip, you notice that sunlight is shining on the area where the oximeter is. Your action will be to:

• A. Set and turn on the alarm of the oximeter
• B. Do nothing since there is no identified problem
• C. Cover the fingertip sensor with a towel or bedsheet
• D. Change the location of the sensor every four hours

Correct answer: B

Rationale: In this scenario, the correct action is to do nothing since there is no identified problem with the sunlight shining on the area where the oximeter is placed. The functionality of the oximeter is not affected by sunlight, so covering it or changing its location unnecessarily could disrupt the monitoring process. Setting the alarm or changing the sensor location every four hours is not indicated in this situation and may lead to unnecessary interventions. It's essential to assess the situation carefully and intervene only when necessary, ensuring that care provided is appropriate and effective.
