Nursing Elites

1. Insulin forces which of the following electrolytes out of the plasma and into the cells?

• A. Calcium
• B. Magnesium
• C. Phosphorus
• D. Potassium

Correct answer: D

Rationale: Insulin forces potassium out of the plasma and into the cells, which can cause hypokalemia. This is because insulin enhances the activity of the sodium-potassium pump in cell membranes, promoting the movement of potassium from the extracellular fluid into the cells. Choices A, B, and C are incorrect as insulin does not directly influence the movement of calcium, magnesium, or phosphorus in the same manner as it does with potassium.

2. What is idiopathic thrombocytopenia purpura?

• A. Highly similar to disseminated intravascular coagulation (DIC).
• B. Caused by the overproduction of platelets.
• C. A bleeding disorder that is characterized by too few platelets.
• D. Treated with immune system-boosting medications.

Correct answer: C

Rationale: Idiopathic thrombocytopenic purpura is a bleeding disorder characterized by a low number of platelets in the blood. This condition is not highly similar to disseminated intravascular coagulation (DIC), which involves abnormal clotting throughout the body (coagulation), leading to depletion of platelets. Choice B is incorrect because idiopathic thrombocytopenic purpura is actually characterized by a decrease in platelet count, not an overproduction. While immune system-boosting medications may be used in some cases, the primary treatment for idiopathic thrombocytopenic purpura focuses on increasing platelet counts or managing symptoms.

3. When developing an educational program for staff regarding a new intravenous pump, what is the correct sequence of actions for a nurse to take?

• A. Develop learning objectives for the program
• B. Identify what skills to teach the staff members
• C. Conduct program evaluation with staff members
• D. Schedule several sessions of the program

Correct answer: B

Rationale: The correct sequence of actions when developing an educational program for staff regarding a new intravenous pump is to first identify what skills to teach the staff members. This step is essential as it sets the foundation for the learning objectives to be developed next. Once the learning objectives are established, scheduling several sessions of the program can be planned accordingly. Finally, after the program has been conducted, program evaluation with staff members should take place to assess the effectiveness of the educational program. Therefore, options A, C, and D are out of sequence, making them incorrect choices.

4. A nurse manager is leading a discussion about ethical dilemmas. Which of the following situations should the nurse manager include as an example of an ethical dilemma?

• A. A visitor experiences a minor burn after spilling coffee
• B. A client receives an operation on the wrong side of her body
• C. A parent wants her 14-year-old adolescent to receive radiation treatment against his will
• D. A nurse witnesses another nurse administer an incorrect medication

Correct answer: C

Rationale: An ethical dilemma involves a situation where moral principles conflict, such as in the case of a parent wanting their adolescent to receive treatment against their will. In option A, a minor burn from spilled coffee does not present a conflict of moral principles. Option B describes a medical error, not necessarily a conflict of moral principles. Option D involves an issue of professional practice and patient safety but does not inherently pose a conflict of moral principles.

5. Select the stage of shock that is accurately paired with its characteristic.

• A. The initial stage of shock: Hyperventilation occurs and the blood pH rises.
• B. The compensatory stage of shock: Hypoxia occurs and lactic acid rises.
• C. The progressive stage of shock: Histamine is released; fluid and proteins leak into surrounding tissues and the blood thickens.
• D. The refractory stage of shock: Potassium ions leak out; sodium ions build up, and metabolic acidosis increases.

Correct answer: C

Rationale: The progressive stage of shock is accurately described as the stage where histamine is released, leading to fluid and proteins leaking into surrounding tissues and the blood thickening. In this stage, the body's compensatory mechanisms are overwhelmed, resulting in a cascade of events that worsen the shock state. Choice A is incorrect as hyperventilation and a rise in blood pH are more characteristic of the compensatory stage. Choice B is incorrect as hypoxia and a rise in lactic acid are more typical of the progressive stage. Choice D is incorrect as the described electrolyte imbalances and metabolic acidosis are more aligned with the refractory stage of shock.
