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.

A nurse is assessing a client who reports taking over-the-counter antacids. Which of the following findings should the nurse identify as a manifestation of hypercalcemia?
- A. Constipation
- B. Decreased urine output
- C. Positive Trousseau's sign
- D. Headache
Correct Answer: A
Rationale: The correct answer is A: Constipation. Hypercalcemia can result from excessive intake of antacids containing calcium carbonate. High levels of calcium in the blood can lead to constipation due to its inhibitory effect on smooth muscle contraction in the intestinal tract. Decreased urine output (choice B) is more indicative of dehydration or renal issues. Positive Trousseau's sign (choice C) is associated with hypocalcemia, not hypercalcemia. Headache (choice D) is a nonspecific symptom and not a typical manifestation of hypercalcemia.
A nurse is providing teaching to a client who has a new prescription for enoxaparin. Which of the following medications for pain relief should the nurse include in the teaching that can be taken concurrently with enoxaparin?
- A. Ibuprofen
- B. Naproxen sodium
- C. Acetaminophen
- D. Aspirin
Correct Answer: C
Rationale: Rationale: Acetaminophen is the correct choice because it does not have an antiplatelet effect like aspirin, ibuprofen, and naproxen sodium. Enoxaparin is an anticoagulant that works by preventing blood clots, so it is safer to take acetaminophen for pain relief as it does not increase the risk of bleeding. Aspirin, ibuprofen, and naproxen sodium can increase the risk of bleeding when taken with enoxaparin due to their antiplatelet effects. Therefore, acetaminophen is the safest option for pain relief while on enoxaparin therapy.
A nurse is caring for a client who has a prescription for total parenteral nutrition (TPN). Which of the following routes of administration should the nurse use?
- A. Subcutaneous
- B. Intravenous
- C. Central venous access device
- D. Midline catheter
Correct Answer: C
Rationale: The correct answer is C: Central venous access device. TPN is a highly concentrated solution that provides all the nutrients a person needs intravenously. A central venous access device allows for the infusion of TPN into a large central vein, such as the superior vena cava, ensuring immediate access to the bloodstream for rapid absorption. Using other routes like subcutaneous (A), intravenous (B), or midline catheter (D) may not be suitable due to the high osmolarity of TPN, which can cause irritation and damage to smaller veins. Therefore, a central venous access device is the most appropriate and safe route for administering TPN.
A nurse accidentally administers the medication metformin instead of metoprolol to a client. Which of the following actions should the nurse take?
- A. Monitor the client's thyroid function levels.
- B. Collect the client's uric acid level.
- C. Obtain the client's HDL level.
- D. Check the client's glucose level.
Correct Answer: D
Rationale: The correct answer is D: Check the client's glucose level. Metformin is a medication used to treat diabetes, so administering it instead of metoprolol could lead to hypoglycemia. Checking the client's glucose level will help determine if the client is experiencing low blood sugar levels due to the medication error. Monitoring thyroid function (A), collecting uric acid levels (B), and obtaining HDL levels (C) are not relevant in this situation and would not address the immediate concern of potential hypoglycemia.
A nurse is preparing to administer the initial dose of penicillin G IM to a client. The nurse should monitor for which of the following as an indication of an allergic reaction following the injection?
- A. Urticaria
- B. Bradycardia
- C. Pallor
- D. Dyspepsia
Correct Answer: A
Rationale: The correct answer is A: Urticaria. Urticaria, or hives, is a classic sign of an allergic reaction. It presents as raised, red, itchy welts on the skin. This occurs due to histamine release in response to the allergen (penicillin in this case). Monitoring for urticaria is crucial as it indicates a potentially serious allergic reaction that may progress to anaphylaxis. Bradycardia (B), Pallor (C), and Dyspepsia (D) are not typically associated with allergic reactions to penicillin. Bradycardia is a slow heart rate, pallor is paleness of the skin, and dyspepsia is indigestion. These symptoms are more likely related to other conditions or side effects rather than an allergic reaction.
