Nursing Elites

1. 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.

2. How can a nurse recognize that a chronic renal failure client's AV shunt is patent?

• A. Absence of a bruit
• B. Presence of a thrill
• C. Blood return from the shunt
• D. Urine output greater than 30 ml/hr

Correct answer: B

Rationale: The correct assessment to determine the patency of an AV shunt in a chronic renal failure client is the presence of a thrill. A thrill is a vibration or buzzing sensation felt over the shunt site, indicating good blood flow through the shunt. While the presence of a bruit is also important for assessing an AV shunt, a thrill is a more specific indicator of patency. Blood return from the shunt is related to cannulation and not necessarily an indicator of patency. Urine output greater than 30 ml/hr is not directly related to the assessment of an AV shunt's patency.

3. During a stress test, a patient complains of severe chest pain. Which of the following medications is the most appropriate to relieve this discomfort?

• A. Aspirin
• B. Diazoxide
• C. Procardia
• D. Mannitol

Correct answer: C

Rationale: In this scenario, the most appropriate medication to relieve severe ischemic chest pain during a stress test is Procardia. Procardia, a calcium channel blocker, is effective in quickly alleviating chest pain by dilating coronary arteries, improving blood flow to the heart muscle. Aspirin, although important for antiplatelet effects, is not the best choice for immediate relief of severe chest pain. Diazoxide is a vasodilator used in hypertensive emergencies, not for acute chest pain. Mannitol is an osmotic diuretic used to reduce intracranial pressure, not for chest pain relief.

4. Which dietary consideration is most important for the nurse to teach to a client with hypothyroidism?

• A. Increase carbohydrate intake
• B. Increase fluid intake
• C. Avoid shellfish
• D. Increase fiber

Correct answer: D

Rationale: The correct answer is to 'Increase fiber.' In hypothyroidism, clients often experience constipation due to decreased metabolic rate. Increasing fiber in the diet can help alleviate constipation. Choice A, 'Increase carbohydrate intake,' is incorrect as there is no specific need to increase carbohydrate intake in hypothyroidism. Choice B, 'Increase fluid intake,' is not directly related to managing hypothyroidism, although adequate hydration is generally important for overall health. Choice C, 'Avoid shellfish,' is commonly associated with hyperthyroidism due to its iodine content, not hypothyroidism.

5. Which sexually transmitted disease, sometimes referred to as the silent STD, is more common than gonorrhea and a leading cause of PID?

• A. Genital herpes.
• B. Trichomoniasis.
• C. Syphilis.
• D. Chlamydia.

Correct answer: D

Rationale: The correct answer is Chlamydia. Chlamydia is a common sexually transmitted infection that can often be asymptomatic, earning it the nickname 'silent STD.' It is more common than gonorrhea and is a leading cause of Pelvic Inflammatory Disease (PID). Genital herpes (Choice A) is a viral infection, not a bacterial STD like chlamydia. Trichomoniasis (Choice B) is a parasitic infection and not commonly associated with causing PID. Syphilis (Choice C) is a bacterial infection but is not as common as chlamydia and is not a leading cause of PID.
