Nursing Elites

1. What are the major electrolytes in the extracellular fluid?

• A. potassium and chloride
• B. potassium and phosphate
• C. sodium and chloride
• D. sodium and phosphate

Correct answer: C

Rationale: The correct answer is sodium and chloride. These two electrolytes are the major components of extracellular fluid. Potassium and phosphate (Choice B) are not the major electrolytes in the extracellular fluid. Potassium is primarily an intracellular ion, and phosphate is more abundant in the intracellular fluid and bones. Sodium and phosphate (Choice D) are also not the major electrolytes in the extracellular fluid. Chloride plays a crucial role in maintaining electrolyte balance and is predominantly found in extracellular fluid alongside sodium.

2. A mother of a newborn notices a nurse placing liquid in her baby's eyes. Which of the following is an inaccurate statement about the need for eyedrops following birth?

• A. Eyedrops following birth help reduce the risk of eye infection.
• B. Eyedrops are required by law.
• C. Eyedrops will keep the eye moist.
• D. Eyedrops are required by law every 6 hours following birth.

Correct answer: D

Rationale: The correct answer is 'Eyedrops are required by law every 6 hours following birth.' This statement is inaccurate because while laws do require the placement of eyedrops, physicians indicate a specific timeframe for their administration. Choice A is correct because eyedrops following birth do help reduce the risk of eye infection by preventing ophthalmia neonatorum. Choice B is incorrect as it implies that eyedrops are mandated solely by law, without considering medical reasons. Choice C is accurate as eyedrops do help keep the eye moist, preventing dryness and discomfort.

3. Ten-year-old Jackie is admitted to the hospital with a medical diagnosis of Rheumatic Fever. She relates a history of 'a sore throat about a month ago.' Bed rest with bathroom privileges is prescribed. Which of the following nursing assessments should be given the highest priority when assessing Jackie's condition?

• A. her response to hospitalization
• B. the presence of a macular rash on her trunk
• C. her cardiac status
• D. the presence of polyarthritis and joint pain

Correct answer: C

Rationale: Monitoring Jackie's cardiac status is of the highest priority in a patient with rheumatic fever. Rheumatic fever can lead to permanent cardiac damage, making it crucial to closely monitor the heart. Assessing for signs of carditis, such as murmurs or other cardiac symptoms, is essential. The second priority is evaluating joint symptoms for the presence of polyarthritis and pain, which are common manifestations of rheumatic fever. While assessing Jackie's response to hospitalization is important for her emotional well-being, it is not the highest priority. The presence of a macular rash, although relevant, is not as high a priority as monitoring cardiac status or assessing joint symptoms.

4. Laboratory tests reveal the following electrolyte values for Mr. Smith: Na 135 mEq/L, Ca 8.5 mg/dL, Cl 102 mEq/L, and K 2.0 mEq/L. Which of the following values should the nurse report to the physician because of its potential risk to the client?

• A. Ca
• B. K
• C. Na
• D. Cl

Correct answer: B

Rationale: The correct answer is 'K.' Normal serum potassium levels range between 3.5 and 5.5 mEq/L. Mr. Smith's potassium level of 2.0 mEq/L is significantly below the normal range, indicating hypokalemia, which can lead to serious risks such as cardiac arrhythmias. The levels of sodium (Na), calcium (Ca), and chloride (Cl) are within normal ranges, so they do not pose an immediate risk to the client's health. Therefore, the nurse should report the low potassium level to the physician for prompt intervention.

5. Assessment of the client with an arteriovenous fistula for hemodialysis should include:

• A. inspection for visible pulsations.
• B. palpation of thrill.
• C. percussion for dullness.
• D. auscultation of blood pressure.

Correct answer: B

Rationale: The correct answer is to palpate for a thrill. A thrill should be present in a functioning arteriovenous fistula (AVF) and indicates good blood flow. The client should be educated to check for this sensation daily at home to monitor the AVF's patency. Visible pulsations are not typically observed in an AVF. Percussion for dullness does not provide relevant information about the AVF. Auscultation of blood pressure is not a standard practice in assessing an AVF. However, auscultation of the AVF for a bruit, a sound indicating turbulent blood flow, is crucial in evaluating the AVF's patency.
