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 are some of the earliest signs and symptoms of Duchenne's muscular dystrophy?

• A. Clumsiness, difficulty running, climbing, and riding a bicycle
• B. Pain and inflammation in the bones
• C. Deformity of the foot
• D. Infection in the joint leading to arthritis

Correct answer: A

Rationale: The correct answer is A: Clumsiness, difficulty running, climbing, and riding a bicycle are some of the earliest signs and symptoms of Duchenne's muscular dystrophy. Duchenne's muscular dystrophy is a genetic disorder characterized by progressive muscle degeneration and weakness. Choices B, C, and D are incorrect because they do not represent the typical early signs and symptoms of Duchenne's muscular dystrophy. Pain and inflammation in the bones (choice B) are more indicative of conditions like osteomyelitis; deformity of the foot (choice C) is characteristic of talipes or clubfoot; and infection in the joint leading to arthritis (choice D) is more aligned with septic joint or supportive arthritis.

3. A nurse reviews the electrolyte results of an assigned client and notes that the potassium level is 5.4 mEq/L. Which of the following would the nurse expect to note on the electrocardiogram as a result of the laboratory value?

• A. ST depression
• B. Inverted T wave
• C. Prominent U wave
• D. Tall peaked T waves

Correct answer: D

Rationale: The correct answer is 'Tall peaked T waves.' Tall peaked T waves are characteristic ECG changes associated with hyperkalemia. In hyperkalemia, the elevated potassium levels affect the myocardium, leading to changes in the ECG. ST depression (Choice A) is more commonly associated with myocardial ischemia or infarction. Inverted T wave (Choice B) is seen in conditions like myocardial ischemia or CNS events. Prominent U wave (Choice C) is typically associated with hypokalemia or certain medications. Therefore, in this scenario, the nurse would expect to note tall peaked T waves on the electrocardiogram due to the elevated potassium level.

4. A charge nurse on an obstetrical unit is preparing the shift assignment. Which of the following clients should be assigned to an RN who has floated from a medical-surgical unit?

• A. A client who is at 32 weeks of gestation and has premature rupture of membranes
• B. A multigravida client who has preeclampsia and is receiving misoprostol for induction of labor
• C. A primigravida client who is 1 day postoperative following a Cesarean section and has a PCA pump
• D. A client who has gestational diabetes and is receiving biweekly nonstress tests

Correct answer: C

Rationale: A nurse who floated from a medical-surgical unit would be appropriate to care for a client who is 1 day postoperative following a Cesarean section and has a PCA pump. This client requires monitoring of the postoperative incision site, pain management through the PCA pump, and assessment for any signs of complications related to the surgery. Assigning this client to an RN with experience in postoperative care aligns with providing specialized and appropriate care. Choices A, B, and D involve conditions or procedures specific to obstetrics that would be better managed by a nurse with obstetrical experience, making them incorrect choices for the floated RN.

5. Why is patient confidentiality significant in healthcare?

• A. Sharing patient information freely
• B. Protecting patient privacy
• C. Ignoring patient consent
• D. Limiting patient access to their own records

Correct answer: B

Rationale: Patient confidentiality is significant in healthcare because it involves protecting patient privacy. Maintaining confidentiality ensures that patients feel safe and secure when sharing sensitive information with healthcare providers. Choice A is incorrect because sharing patient information freely would violate confidentiality. Choice C is incorrect because ignoring patient consent goes against ethical principles. Choice D is incorrect because limiting patient access to their own records does not relate directly to the concept of patient confidentiality.
