Nursing Elites

1. Which of the following lab results is most indicative of dehydration?

• A. Low sodium levels.
• B. Elevated creatinine levels.
• C. Low potassium levels.
• D. High blood glucose levels.

Correct answer: B

Rationale: Elevated creatinine levels are indicative of dehydration because when the body is dehydrated, the kidneys concentrate urine to preserve fluid, leading to higher levels of creatinine. Low sodium levels (Choice A) can be seen in conditions like hyponatremia but are not specific to dehydration. Low potassium levels (Choice C) are more commonly associated with conditions like hypokalemia. High blood glucose levels (Choice D) are typically seen in diabetes and are not specific indicators of dehydration.

2. A client who has received sodium bicarbonate in large amounts is at risk for metabolic alkalosis. For which of the following signs and symptoms does the nurse assess this client?

• A. Disorientation and dyspnea
• B. Drowsiness, headache, and tachypnea
• C. Tachypnea, dizziness, and paresthesias
• D. Dysrhythmias and decreased respiratory rate and depth

Correct answer: D

Rationale: The correct answer is D. A client with metabolic alkalosis may present with dysrhythmias and a decreased respiratory rate and depth as the body tries to compensate by retaining carbon dioxide. Options A, B, and C do not typically correlate with the signs and symptoms of metabolic alkalosis. Disorientation, dyspnea, drowsiness, headache, tachypnea, dizziness, and paresthesias are not commonly associated with metabolic alkalosis. Therefore, they are incorrect choices.

3. A client is placed on a mechanical ventilator following a cerebral hemorrhage, and vecuronium bromide (Norcuron) 0.04 mg/kg q12 hours IV is prescribed. What is the priority nursing diagnosis for this client?

• A. Impaired communication related to paralysis of skeletal muscles.
• B. High risk for infection related to increased intracranial pressure.
• C. Potential for injury related to impaired lung expansion.
• D. Social isolation related to inability to communicate.

Correct answer: A

Rationale: The priority nursing diagnosis for a client on a mechanical ventilator receiving vecuronium bromide is 'Impaired communication related to paralysis of skeletal muscles.' Vecuronium is a skeletal muscle relaxant that causes diaphragmatic paralysis, leading to the inability of the client to communicate effectively. This is a crucial nursing concern as it impacts the client's ability to express needs and participate in care. Option B 'High risk for infection related to increased intracranial pressure' is not the priority in this scenario as the client's condition is related to the effects of the medication and mechanical ventilation, not directly to increased intracranial pressure. Option C 'Potential for injury related to impaired lung expansion' is important but not the priority over impaired communication. Option D 'Social isolation related to inability to communicate' is not the priority nursing diagnosis in this situation as it focuses more on psychosocial aspects rather than the immediate physiological concern of communication impairment.

4. Which of the following lab values would be most concerning in a patient receiving heparin therapy?

• A. Elevated hemoglobin levels.
• B. Low platelet count.
• C. High potassium levels.
• D. Low sodium levels.

Correct answer: B

Rationale: A low platelet count is most concerning in patients receiving heparin therapy due to the risk of heparin-induced thrombocytopenia. Heparin can sometimes cause a drop in platelet count, leading to a potentially serious condition where blood does not clot as it should. This can result in excessive bleeding or clot formation in blood vessels. Elevated hemoglobin levels, high potassium levels, and low sodium levels are not typically associated with heparin therapy and are less likely to cause immediate concerns or complications in this context.

5. A nurse teaches clients about the difference between urge incontinence and stress incontinence. Which statements should the nurse include in this education? (Select all that apply.)

• A. Urge incontinence involves a post-void residual volume less than 50 mL.
• B. Stress incontinence occurs due to weak pelvic floor muscles.
• C. Stress incontinence usually occurs in people with dementia.
• D. Urge incontinence can be managed by increasing fluid intake.

Correct answer: B

Rationale: The correct statement to include in the education about urge incontinence and stress incontinence is choice B. Stress incontinence occurs due to weak pelvic floor muscles or urethral sphincter, leading to the inability to tighten the urethra sufficiently to overcome increased detrusor pressure. This condition is common after childbirth when pelvic muscles are stretched and weakened. Urge incontinence, on the other hand, is characterized by the inability to suppress the contraction signal from the detrusor muscle. It is often associated with abnormal detrusor contractions, which can be due to neurological abnormalities rather than post-void residual volume. Choice A is incorrect because urge incontinence is not defined by post-void residual volume. Choice C is incorrect as stress incontinence is not usually linked to dementia. Choice D is incorrect because increasing fluid intake is not a management strategy for urge incontinence.
