Nursing Elites

1. A nurse is reviewing the laboratory values for a client who is receiving a continuous IV heparin infusion and has an aPTT of 90 seconds. Which of the following actions should the nurse prepare to take?

• A. Administer vitamin K
• B. Reduce the infusion rate
• C. Give the client a low-dose aspirin
• D. Request an INR

Correct answer: B

Rationale: An aPTT of 90 seconds is elevated, indicating a risk of bleeding due to excessive anticoagulation. The appropriate action is to reduce the infusion rate of heparin to prevent further complications. Administering vitamin K is not indicated for an elevated aPTT due to heparin therapy. Giving the client a low-dose aspirin can further increase the risk of bleeding when combined with heparin. Requesting an INR is not necessary for monitoring heparin therapy; aPTT is the more specific test for assessing heparin's therapeutic effect. Therefore, the correct action for the nurse to prepare to take is to reduce the infusion rate of heparin.

2. A nurse in an outpatient facility is assessing a client who is prescribed furosemide 40 mg daily, but the client reports she has been taking extra doses to promote weight loss. Which of the following indicates she is dehydrated?

• A. Urine specific gravity of 1.035
• B. Oliguria
• C. Increased urine concentration
• D. Dry mucous membranes

Correct answer: A

Rationale: The correct answer is A: Urine specific gravity of 1.035. A urine specific gravity greater than 1.030 indicates dehydration as the kidneys conserve water in response to dehydration. Choice B, oliguria, refers to decreased urine output, which can be a sign of dehydration but is not specific to it. Choice C, increased urine concentration, is a general term and does not directly indicate dehydration. Choice D, dry mucous membranes, can be a sign of dehydration but is not as specific as a urine specific gravity greater than 1.030.

3. A nurse is providing teaching to a client who has cirrhosis and a new prescription for lactulose. The nurse should instruct the client that lactulose has which of the following therapeutic effects?

• A. Increases blood pressure
• B. Prevents esophageal bleeding
• C. Decreases heart rate
• D. Reduces ammonia levels

Correct answer: D

Rationale: The correct answer is D: Reduces ammonia levels. Lactulose is used to reduce blood ammonia levels in clients with hepatic encephalopathy. Options A, B, and C are incorrect because lactulose does not have the therapeutic effect of increasing blood pressure, preventing esophageal bleeding, or decreasing heart rate.

4. A nurse is caring for a client who has a new prescription for tamoxifen. The nurse should recognize that tamoxifen has which of the following therapeutic effects?

• A. Antiestrogenic
• B. Antimicrobial
• C. Androgenic
• D. Anti-inflammatory

Correct answer: A

Rationale: Tamoxifen is an antiestrogen medication used primarily in the treatment and prevention of breast cancer. It works by blocking the effects of estrogen in the breast tissue, thereby acting as an antiestrogenic agent. This makes choice A the correct answer. Choice B, antimicrobial, is incorrect as tamoxifen does not possess antimicrobial properties and is not used to treat infections. Choice C, androgenic, is incorrect as tamoxifen has antiestrogenic effects, not androgenic effects. Choice D, anti-inflammatory, is incorrect as tamoxifen's main therapeutic action is antiestrogenic rather than anti-inflammatory.

5. A nurse is providing teaching to a client who has a new prescription for hydrochlorothiazide 50 mg PO daily to treat hypertension. Which of the following instructions should the nurse include in the teaching?

• A. Take hydrochlorothiazide as needed for edema.
• B. Check your weight once weekly.
• C. Take the hydrochlorothiazide on an empty stomach.
• D. Take the hydrochlorothiazide in the morning.

Correct answer: D

Rationale: The correct answer is to take hydrochlorothiazide in the morning. This medication is usually advised to be taken in the morning to prevent nocturia, which is excessive urination at night. Option A is incorrect because hydrochlorothiazide should be taken daily as prescribed, not as needed for edema. Option B is incorrect as monitoring weight weekly may not be specifically related to hydrochlorothiazide therapy. Option C is incorrect as hydrochlorothiazide does not need to be taken on an empty stomach.
