Nursing Elites

1. A woman who takes pyridostigmine for myasthenia gravis (MG) arrives at the emergency department complaining of extreme muscle weakness. Her adult daughter tells the nurse that since yesterday her mother has been unable to smile. Which assessment finding warrants immediate intervention by the nurse?

• A. Uncontrollable drooling.
• B. Inability to raise voice.
• C. Tingling of extremities.
• D. Eyelid drooping.

Correct answer: A

Rationale: Uncontrollable drooling can be a sign of a myasthenic crisis, which requires immediate medical intervention to prevent respiratory failure. Drooling indicates difficulty in swallowing, which can lead to aspiration and respiratory compromise. Inability to raise voice (choice B) and tingling of extremities (choice C) are not typically associated with myasthenic crisis. Although eyelid drooping (choice D) is a common symptom of myasthenia gravis, it is not as urgent as uncontrollable drooling in indicating a potential crisis.

2. A client with diabetes mellitus is admitted with a blood glucose level of 600 mg/dl and is unresponsive. Which laboratory value is most concerning?

• A. Serum potassium of 3.0 mEq/L
• B. Serum glucose of 200 mg/dl
• C. Serum pH of 7.30
• D. Serum sodium of 135 mEq/L

Correct answer: C

Rationale: In a client with Hyperosmolar Hyperglycemic State (HHS), a serum pH of 7.30 is the most concerning value as it indicates acidosis, a life-threatening condition that requires immediate intervention. Choices A, B, and D are not the most concerning in this scenario. A low serum potassium level (Choice A) may be expected due to cellular shift in hyperglycemia, a serum glucose level of 200 mg/dl (Choice B) is not as concerning compared to the extremely high initial glucose level, and a serum sodium level of 135 mEq/L (Choice D) is within the normal range and not the immediate priority.

3. The nurse is assessing a client with left-sided heart failure. Which laboratory value is most concerning?

• A. Serum creatinine of 1.5 mg/dL
• B. Serum sodium of 136 mEq/L
• C. Serum potassium of 5.5 mEq/L
• D. Hemoglobin of 12 g/dL

Correct answer: C

Rationale: A serum potassium level of 5.5 mEq/L is most concerning in a client with left-sided heart failure as it indicates hyperkalemia, requiring immediate intervention. Hyperkalemia can lead to life-threatening cardiac arrhythmias, which can exacerbate heart failure. Serum creatinine of 1.5 mg/dL is slightly elevated but not as immediately concerning as hyperkalemia. Serum sodium of 136 mEq/L is within the normal range. Hemoglobin of 12 g/dL is also within the normal range and not directly related to the client's left-sided heart failure.

4. An adult client comes to the clinic and reports his concern over a lump that 'just popped up on my neck about a week ago.' In performing an examination of the lump, the nurse palpates a large, non-tender, hardened left subclavian lymph node. There is no overlying tissue inflammation. What do these findings suggest?

• A. Malignancy
• B. Infection
• C. Benign cyst
• D. Lymphadenitis

Correct answer: A

Rationale: The findings of a large, non-tender, hardened lymph node, especially in the absence of overlying tissue inflammation, are indicative of malignancy. These characteristics raise suspicion for cancer, prompting the need for further investigation. Choice B, Infection, is incorrect because infection would typically present as a tender and possibly swollen lymph node. Choice C, Benign cyst, is incorrect as cysts are usually soft and movable. Choice D, Lymphadenitis, is incorrect as lymphadenitis usually presents with tender and enlarged lymph nodes in response to an infection.

5. The nurse is caring for a client with acute respiratory distress syndrome (ARDS) who is receiving mechanical ventilation. Which assessment finding requires immediate intervention?

• A. Oxygen saturation of 90%
• B. Respiratory rate of 28 breaths per minute
• C. Tidal volume of 300 ml
• D. Blood pressure of 110/70 mmHg

Correct answer: C

Rationale: The correct answer is C. A tidal volume of 300 ml is concerning in a client with ARDS on mechanical ventilation because it indicates hypoventilation, which can lead to inadequate gas exchange and worsening respiratory status. This finding requires immediate intervention to optimize ventilation and oxygenation. Options A, B, and D are not as critical in this scenario. An oxygen saturation of 90% may be acceptable depending on the client's baseline condition and the target range set by the healthcare provider. A respiratory rate of 28 breaths per minute is slightly elevated but may not be immediately alarming. A blood pressure of 110/70 mmHg is within normal limits and does not require urgent intervention.
