A nurse is preparing to administer heparin 8,000 units subcutaneously every eight hours. The amount available is heparin injection 10,000 units/mL. How many milliliters should the nurse administer per dose? (Round the answer to the nearest tenth)
- A. 0.8 mL
- B. 0.9 mL
- C. 10.0 mL
- D. 98.0 mL
Correct Answer: A
Rationale: To determine the volume of heparin to administer per dose, divide the prescribed dose (8,000 units) by the concentration of heparin available (10,000 units/mL). 8000 units / 10000 units/mL = 0.8 mL. Therefore, the nurse should administer 0.8 mL per dose. Choice B, 0.9 mL, is incorrect as the correct calculation results in 0.8 mL. Choices C and D are significantly higher and incorrect, indicating an inaccurate calculation.

A client with congestive heart failure taking digoxin reports nausea and refuses to eat breakfast. Which action should the nurse take first?
- A. Encourage the client to eat the toast on the breakfast tray.
- B. Administer an antiemetic.
- C. Inform the client's provider.
- D. Check the client's apical pulse.
Correct Answer: D
Rationale: The correct action for the nurse to take first is to check the client's apical pulse. Nausea can be a sign of digoxin toxicity, and one of the early signs of digoxin toxicity is changes in the pulse rate. By checking the client's apical pulse, the nurse can assess if the digoxin level is too high. Encouraging the client to eat or administering an antiemetic may not address the underlying issue of digoxin toxicity. While informing the provider is important, assessing the client's condition through checking the apical pulse should be the immediate priority.
A healthcare professional is planning to administer diltiazem via IV bolus to a client who has atrial fibrillation. When assessing the client, the healthcare professional should recognize that which of the following findings is a contraindication to the administration of diltiazem?
- A. Hypotension
- B. Tachycardia
- C. Decreased level of consciousness
- D. History of diuretic use
Correct Answer: A
Rationale: Diltiazem, a calcium channel blocker, can cause hypotension. Administering it to a client who already has hypotension could exacerbate this condition. Therefore, hypotension is a contraindication to the administration of diltiazem.
Incorrect Choices:
B) Tachycardia is not a contraindication for administering diltiazem in atrial fibrillation as it is commonly used to control the heart rate.
C) Decreased level of consciousness may require evaluation but is not a direct contraindication to diltiazem administration.
D) History of diuretic use is not a contraindication if the client is not currently experiencing hypotension.
A nurse is caring for an older adult client who has a prescription for zolpidem at bedtime to promote sleep. The nurse should plan to monitor the client for which of the following adverse effects?
- A. Ecchymosis
- B. Decreased urine output
- C. Increased blood pressure
- D. Dizziness
Correct Answer: D
Rationale: The correct answer is D: Dizziness. Zolpidem is known to cause dizziness, especially in older adults. This adverse effect can increase the risk of falls and injuries in the elderly population. Monitoring for dizziness is crucial to ensure patient safety. Choice A, Ecchymosis, is the development of bruising and is not a common adverse effect of zolpidem. Choices B and C, Decreased urine output and Increased blood pressure, are not typically associated with zolpidem use. Therefore, they are incorrect choices in this scenario.
When administering subcutaneous epinephrine for a client experiencing anaphylaxis, what adverse effect should the nurse monitor for?
- A. Hypotension
- B. Hyperthermia
- C. Hypoglycemia
- D. Tachycardia
Correct Answer: D
Rationale: The correct adverse effect to monitor for when administering subcutaneous epinephrine for anaphylaxis is tachycardia. Epinephrine stimulates adrenergic receptors, leading to an increased heart rate (tachycardia). Hypotension (Choice A) is less likely due to the vasoconstrictive effects of epinephrine. Hyperthermia (Choice B) and hypoglycemia (Choice C) are not commonly associated with epinephrine administration for anaphylaxis.
A nurse is caring for a client who has a new prescription for ergotamine. The nurse should recognize that ergotamine is administered to treat which of the following conditions?
- A. Raynaud's phenomenon
- B. Migraine headaches
- C. Ulcerative colitis
- D. Anemia
Correct Answer: B
Rationale: Ergotamine is used to treat migraine headaches by constricting blood vessels in the brain. Therefore, the correct answer is B. Choice A, Raynaud's phenomenon, is incorrect as ergotamine is not indicated for this condition. Choice C, Ulcerative colitis, is incorrect as ergotamine is not used to treat this gastrointestinal disorder. Choice D, Anemia, is incorrect as ergotamine is not prescribed for anemia.
