Nursing Elites

1. The nurse is teaching a nursing student about the minimal effective concentration (MEC) of antibiotics. Which statement by the nursing student indicates understanding of this concept?

• A. A serum drug level greater than the MEC ensures that the drug is bacteriostatic.
• B. A serum drug level greater than the MEC broadens the spectrum of the drug.
• C. A serum drug level greater than the MEC helps eradicate bacterial infections.
• D. A serum drug level greater than the MEC increases the therapeutic index.

Correct answer: C

Rationale: The MEC is the minimum amount of drug needed to halt the growth of a microorganism. A level greater than the MEC helps eradicate infections. Drugs at or above the MEC are usually bactericidal, not bacteriostatic. Therefore, choice A is incorrect. Broadening the spectrum of a drug refers to its range of activity against different microorganisms, which is not directly related to MEC. Thus, choice B is incorrect. Increasing the therapeutic index involves maximizing the effectiveness of a drug while minimizing its toxicity, which is not specifically related to MEC. Therefore, choice D is also incorrect.

2. While assessing a female client who is chronically fatigued and was recently diagnosed with adrenal insufficiency, the client tells the nurse that she is very nervous that her hospitalization will cause her to lose her job. Which intervention should the nurse implement first?

• A. Teach the client about the risk for infection.
• B. Offer support and care measures to reduce anxiety and stress.
• C. Encourage the client to rest quietly to reduce fatigue.
• D. Place a referral to social services to discuss financial options.

Correct answer: B

Rationale: In this scenario, the priority intervention for the nurse is to offer support and care measures to reduce anxiety and stress. Addressing the client's emotional distress is crucial as the stress can exacerbate adrenal insufficiency. While teaching the client about the risk for infection (Choice A) is important, addressing the immediate emotional needs takes precedence. Encouraging the client to rest quietly (Choice C) is beneficial but does not directly address the client's current distress about job loss. Referring the client to social services (Choice D) for financial options is important, but at this moment, addressing the client's anxiety is the priority to promote emotional well-being.

3. The healthcare provider notes a blood pressure of 160/90 mm Hg in a patient taking a thiazide diuretic. The patient reports taking an herbal medication that a friend recommended. Which herbal product is likely, given this patient’s blood pressure?

• A. Ginkgo
• B. Hawthorn
• C. Licorice
• D. St. John’s wort

Correct answer: A

Rationale: The correct answer is A: Ginkgo. Increased blood pressure can result when ginkgo is used in combination with a thiazide diuretic. Option B (Hawthorn) is incorrect because hawthorn is more commonly associated with lowering blood pressure. Option C (Licorice) is incorrect because licorice can lead to sodium and water retention, potentially exacerbating hypertension. Option D (St. John’s wort) is incorrect as it is not typically associated with significant blood pressure effects.

4. The client has had a femoral-popliteal bypass surgery 6 hours ago. Which assessment provides the most accurate information about the client's postoperative status?

• A. Radial pulse.
• B. Femoral pulse.
• C. Apical pulse.
• D. Dorsalis pedis pulse.

Correct answer: D

Rationale: Assessing the dorsalis pedis pulse is crucial after a femoral-popliteal bypass surgery to determine adequate circulation distal to the surgical site. A strong dorsalis pedis pulse indicates sufficient blood flow to the foot, which is essential for monitoring postoperative status. The radial pulse (A) is not the most relevant assessment as it does not provide direct information on circulation in the lower extremities. The femoral pulse (B) may not accurately reflect circulation distal to the surgical site. The apical pulse (C) is used primarily to assess the heartbeat and cardiac function, not circulation in the lower extremities.

5. When preparing a client who has had a total laryngectomy for discharge, what instruction is most important for the nurse to include in the discharge teaching?

• A. Recommend that the client carry suction equipment at all times.
• B. Instruct the client to have writing materials with them at all times.
• C. Tell the client to carry a medic alert card stating that they are a total neck breather.
• D. Tell the client not to travel alone.

Correct answer: C

Rationale: The most crucial instruction for a client who has had a total laryngectomy is to carry a medic alert card stating that they are a total neck breather. This is important because if they experience a cardiac arrest, mouth-to-neck breathing may be required. Choice A about carrying suction equipment is not the most critical as the client may not always need it. Choice B is not as essential as having a medic alert card. Choice D is not directly related to the client's safety due to their laryngectomy.
