Nursing Elites

1. Which laboratory test should the nurse monitor to determine the effectiveness of heparin therapy for a client with deep vein thrombosis?

• A. Platelet count
• B. Prothrombin time (PT)
• C. Activated partial thromboplastin time (aPTT)
• D. Hemoglobin and hematocrit

Correct answer: C

Rationale: The activated partial thromboplastin time (aPTT) is the specific laboratory test used to monitor the effectiveness of heparin therapy in patients with deep vein thrombosis. It measures the time it takes for blood to clot and is crucial in assessing the therapeutic range of heparin. Platelet count, prothrombin time (PT), and hemoglobin and hematocrit levels are important parameters in assessing coagulation and blood status but do not directly indicate the effectiveness of heparin therapy.

2. Heparin sodium is prescribed for the client. The nurse expects that the healthcare provider will prescribe which of the following to monitor for a therapeutic effect of the medication?

• A. Hematocrit level
• B. Hemoglobin level
• C. Prothrombin time (PT)
• D. Activated partial thromboplastin time (aPTT)

Correct answer: D

Rationale: The correct answer is D, activated partial thromboplastin time (aPTT). Heparin affects the intrinsic pathway of coagulation. Monitoring aPTT helps ensure that heparin sodium is within the therapeutic range to prevent clot formation. Hematocrit and hemoglobin levels assess red blood cell concentrations and are not specific to monitoring heparin therapy. Prothrombin time (PT) is used to monitor the therapeutic effect of warfarin sodium, which affects the extrinsic pathway of coagulation, not heparin.

3. A client is being educated about the use of levodopa-carbidopa (Sinemet) for Parkinson's disease. Which statement by the client indicates a need for further teaching?

• A. I should avoid taking the medication with a high-protein meal.
• B. I may experience dizziness when getting up quickly.
• C. I might notice a darkening of my urine.
• D. I should report any uncontrolled movements to my healthcare provider.

Correct answer: A

Rationale: The correct answer is A. Levodopa-carbidopa (Sinemet) should not be taken with a high-protein meal as protein can interfere with the absorption of the medication. It is recommended to take it on an empty stomach or with a light meal. Choices B, C, and D are accurate statements regarding potential side effects and actions to take while on levodopa-carbidopa therapy, indicating a good understanding by the client.

4. Phenazopyridine hydrochloride (Pyridium) is prescribed for a client for symptomatic relief of pain resulting from a lower urinary tract infection. The nurse reinforces to the client:

• A. To take the medication after meals
• B. To take the medication before meals
• C. To discontinue the medication if a headache occurs
• D. That a reddish-orange discoloration of the urine may occur

Correct answer: D

Rationale: The nurse should instruct the client that a reddish-orange discoloration of urine may occur. The nurse should also educate the client that this discoloration can stain fabric. It is recommended to take the medication after meals to reduce the possibility of gastrointestinal upset. While a headache is an occasional side effect of the medication, it does not warrant discontinuation of the medication.

5. Intravenous heparin therapy is prescribed for a client. While implementing this prescription, a nurse ensures that which of the following medications is available on the nursing unit?

• A. Protamine sulfate
• B. Potassium chloride
• C. Phytonadione (vitamin K)
• D. Aminocaproic acid (Amicar)

Correct answer: A

Rationale: Protamine sulfate is the antidote for heparin, working to reverse its effects in case of excessive bleeding. It should be readily available when administering heparin to manage any potential bleeding complications effectively. Potassium chloride is not the antidote for heparin and is typically used to correct low potassium levels. Phytonadione (vitamin K) is used to reverse the effects of warfarin, not heparin. Aminocaproic acid (Amicar) is used to treat or prevent excessive bleeding but is not the antidote for heparin.
