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. A nurse working in the emergency department is assessing several clients. Which of the following clients is the highest priority?

• A. A client who reports right-sided flank pain and is diaphoretic
• B. A client who has active bleeding from a puncture wound of the left groin area
• C. A client who has a raised red skin rash on his arms, neck, and face
• D. A client who reports shortness of breath and left neck and shoulder pain

Correct answer: D

Rationale: The correct answer is D because shortness of breath with referred pain may indicate a serious condition, such as a cardiac event or pulmonary embolism, making this the highest priority. Option A, flank pain with diaphoresis, could suggest kidney-related issues but is not as immediately life-threatening as compromised breathing. Option B, active bleeding, though serious, can usually be controlled with proper interventions. Option C, a raised red skin rash, may indicate an allergic reaction but is not as urgent as respiratory distress with neck and shoulder pain.

3. What does the mnemonic PERLA stand for in the assessment of the eyes?

• A. Pupils equally reactive to light and accommodation
• B. Patient eyes are equally recessed and responsive to light and acuity
• C. Patient eyes are equally responsive to light and acuity
• D. Pupils equally reactive to light and acuity

Correct answer: A

Rationale: The correct answer is A: 'Pupils equally reactive to light and accommodation.' PERLA is a mnemonic used in eye assessments to check for Pupils being equally reactive to Light and Accommodation. Choice B is incorrect as it includes irrelevant information about the eyes being recessed. Choice C is incorrect as it is missing the mention of pupils and accommodation. Choice D is incorrect as it misses the mention of accommodation.

4. Which atrioventricular heart block is also referred to as Mobitz II?

• A. Third-degree atrioventricular heart block
• B. Second-degree atrioventricular heart block
• C. First-degree atrioventricular heart block
• D. Complete heart block

Correct answer: B

Rationale: The correct answer is B. Second-degree atrioventricular heart block is also known as Mobitz II. In Mobitz II, some atrial impulses are blocked from reaching the ventricles, resulting in occasional dropped beats. Third-degree atrioventricular heart block is known as complete heart block, where no atrial impulses reach the ventricles. First-degree atrioventricular heart block is a condition where there is delayed conduction between the atria and ventricles but all atrial impulses are eventually conducted to the ventricles.

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.
