A nurse is preparing to administer 4,000 units of heparin subcutaneously to a client who has deep-vein thrombosis. Available is heparin 10,000 units/mL. How many mL of heparin should the nurse administer? (Round to the nearest tenth.)
Correct Answer: 0.4
Rationale: To calculate the mL of heparin to administer, use the formula: desired dose (4,000 units) ÷ concentration (10,000 units/mL) = X mL. 4,000 ÷ 10,000 = 0.4 mL. The correct answer is 0.4 mL because it accurately represents the calculated dose needed for the client. Other choices are incorrect as they do not align with the correct calculation.

Complete the following sentence by using the lists of options. Upon analyzing the assessment findings, the nurse identifies that the client is at risk for Select... due to the Select...
- A. concurrent medication use
- B. recent illness
- C. activity level
Correct Answer: A
Rationale: The correct answer is A: concurrent medication use. The nurse identifies the client is at risk for adverse drug interactions or side effects due to the potential interactions between medications. Recent illness (B) may impact the client's health but does not specifically relate to medication use. Activity level (C) is important but does not directly indicate medication risk. Without options D, E, F, and G, they cannot be considered as potential correct choices.
A nurse is caring for a client who has a new diagnosis of benign prostate hypertrophy and a prescription for doxazosin. The client tells the nurse, 'I do not take this medication. I would prefer a natural therapy.' Which of the following supplements should the nurse suggest the client discuss with the provider?
- A. Black cohosh
- B. Garlic
- C. Feverfew
- D. Saw palmetto
Correct Answer: D
Rationale: The correct answer is D: Saw palmetto. Saw palmetto is commonly used as a natural remedy for benign prostate hypertrophy due to its potential benefits in reducing symptoms. It works by decreasing inflammation and promoting the shrinkage of the prostate gland. The nurse should suggest discussing saw palmetto with the provider as it aligns with the client's preference for natural therapy.
Choice A: Black cohosh is not typically used for prostate issues but rather for menopausal symptoms in women.
Choice B: Garlic is not specifically indicated for benign prostate hypertrophy and is more commonly known for its cardiovascular benefits.
Choice C: Feverfew is primarily used for migraine headaches and has no direct association with prostate health.
In summary, saw palmetto is the most appropriate supplement to suggest as it targets the client's condition effectively compared to the other options provided.
A nurse is caring for a client who is to receive potassium replacement. The provider's prescription reads, 'Potassium chloride 30 mEq in 0.9% sodium chloride 100 mL IV over 30 min.' Which of the following reasons should the nurse clarify this prescription with the provider?
- A. Potassium chloride should be diluted in dextrose 5% in water.
- B. The potassium infusion rate is too rapid.
- C. Another formulation of potassium should be given IV.
- D. The client should be treated by giving potassium by IV bolus.
Correct Answer: B
Rationale: Correct Answer: B
Rationale:
1. Potassium chloride infusion rate should not exceed 10 mEq/hr to prevent hyperkalemia and cardiac arrhythmias.
2. In this case, 30 mEq in 100 mL over 30 min exceeds the safe rate.
3. Clarification is needed to adjust the infusion rate to avoid potential harm.
4. Other choices are incorrect as dextrose dilution, different formulations, and IV bolus are not the primary concerns.
A nurse is preparing to administer enoxaparin to a client. Which of the following actions should the nurse take?
- A. Apply firm pressure to the injection site following administration
- B. Administer the medication into the client's muscle
- C. Expel the air bubble from the syringe prior to injection
- D. Insert the syringe needle halfway into the client's skin
Correct Answer: A
Rationale: Correct Answer: A: Apply firm pressure to the injection site following administration.
Rationale: Applying firm pressure to the injection site following administration of enoxaparin helps minimize the risk of bleeding, as enoxaparin is an anticoagulant medication. This pressure promotes clot formation and reduces the likelihood of bruising or hematoma formation at the injection site.
Summary of other choices:
B: Administer the medication into the client's muscle - Incorrect. Enoxaparin is a subcutaneous medication, not meant for intramuscular administration.
C: Expel the air bubble from the syringe prior to injection - Good practice but not directly related to the administration of enoxaparin.
D: Insert the syringe needle halfway into the client's skin - Incorrect. The needle should be fully inserted for proper subcutaneous injection.
A nurse is providing teaching to a client who has a new prescription for clozapine. Which of the following statements should the nurse include in the teaching?
- A. Diarrhea is a common adverse effect of this medication.
- B. Ringing in the ears is an expected adverse effect of this medication.
- C. Notify your provider if you develop a fever while taking this medication.
- D. You might experience weight loss while taking this medication.
Correct Answer: C
Rationale: The correct answer is C: Notify your provider if you develop a fever while taking this medication. This is important because clozapine can cause a serious condition called agranulocytosis, which can lead to a fever. The nurse should emphasize the significance of monitoring for fever and promptly notifying the healthcare provider. Choice A is incorrect because diarrhea is not a common adverse effect of clozapine. Choice B is incorrect as ringing in the ears is not an expected adverse effect. Choice D is incorrect because weight gain, not weight loss, is a common side effect of clozapine.
