Nursing Elites

1. 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.

2. Which of the following joints normally allows 360-degree circumflexion?

• A. The knee
• B. The shoulder
• C. The elbow
• D. The fingertips

Correct answer: B

Rationale: The correct answer is B: The shoulder. The shoulder joint is a ball-and-socket joint that allows for a wide range of motion, including 360-degree circumflexion. This joint provides flexibility and mobility in various directions. Choice A, the knee joint, primarily allows flexion and extension but does not have a 360-degree circumflexion. Choice C, the elbow joint, is a hinge joint that permits flexion and extension but not circumflexion. Choice D, the fingertips, do not form a specific joint that allows circumflexion; rather, they have joints that enable bending and straightening movements.

3. Clients with type 1 diabetes may require which of the following changes to their daily routine during periods of infection?

• A. No change
• B. Less insulin
• C. More insulin
• D. Oral antidiabetic agents

Correct answer: C

Rationale: During periods of infection, clients with type 1 diabetes may require more insulin to manage the increased blood glucose levels caused by stress and illness. Insulin needs often rise during infections due to the body's increased resistance to the effects of insulin. Therefore, increasing insulin doses is crucial to maintain blood glucose control. Choices A, B, and D are incorrect. Option A ('No change') is inaccurate because during infections, insulin requirements typically increase. Option B ('Less insulin') is incorrect as the body's increased insulin resistance during infections usually necessitates higher insulin doses. Option D ('Oral antidiabetic agents') is not suitable for type 1 diabetes management as these medications are primarily used for type 2 diabetes.

4. Which skin disorder most closely resembles and mimics dandruff?

• A. Lice infestation
• B. Scabies
• C. Dermatitis
• D. Acne vulgaris

Correct answer: C

Rationale: Dermatitis can closely resemble and mimic dandruff due to similar symptoms like flaking and itching. Lice infestation (choice A) is characterized by the presence of lice and their eggs attached to the hair shaft, different from dandruff. Scabies (choice B) is a contagious skin condition caused by mites, presenting as burrows, rashes, and intense itching, not typically resembling dandruff. Acne vulgaris (choice D) is a skin condition involving hair follicles and sebaceous glands, manifesting as pimples and inflammation, which is distinct from dandruff.

5. Which of the following is the best argument for lower patient-to-nurse ratio?

• A. The more patients a nurse has, the better the nurse will be at catching early warning signs.
• B. Greater patient-to-nurse ratios decrease patient mortality.
• C. Adequate nurse levels do not impact the prevalence of urinary tract infections.
• D. Community nursing ratios do not impact Methicillin-resistant Staphylococcus aureus (MRSA) rates.

Correct answer: B

Rationale: The best argument for lower patient-to-nurse ratios is that they decrease patient mortality. Choice A is incorrect because having more patients can lead to increased workload and decreased attention per patient. Choice C is incorrect as adequate nurse levels can indeed impact the prevalence of infections. Choice D is incorrect as community nursing ratios can impact MRSA rates due to potential transmission risks in healthcare settings.
