Heparin 20,000 units in 500 ml D5W at 50 ml/hour has been infusing for 5.5 hours. How much heparin has the client received?
- A. 11,000 units.
- B. 13,000 units.
- C. 15,000 units.
- D. 17,000 units.
Correct Answer: A
Rationale: To calculate the total amount of heparin received, multiply the infusion rate (50 ml/hour) by the total infusion time (5.5 hours). This results in 275 ml of the solution infused. Since there are 20,000 units of heparin in 500 ml, there are 800 units per ml. Therefore, 275 ml contains 220,000 units. However, the heparin is diluted in 500 ml, so the client has received half of this amount, which is 110,000 units. Therefore, the correct answer is 11,000 units. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the provided information.

During a skin assessment, a client expresses concern about skin cancer due to a lesion on the anterior thigh. Which of the following findings should the nurse report to the provider as a possible indication of a skin malignancy?
- A. An uneven shape
- B. A uniformly colored lesion
- C. A lesion that is small and flat
- D. A lesion that is less than 1 cm in diameter
Correct Answer: A
Rationale: An uneven shape of a lesion is a common characteristic of malignant skin lesions. Asymmetric or irregularly shaped lesions are concerning for skin cancer and should be reported promptly for further evaluation and management. Choice B, a uniformly colored lesion, is more indicative of a benign lesion as malignant lesions often exhibit variations in color. Choice C, a lesion that is small and flat, does not necessarily indicate malignancy by itself. Choice D, a lesion that is less than 1 cm in diameter, is more suggestive of a benign lesion, as malignant lesions are typically larger in size.
During assessment, what is an indication of thrombophlebitis in a client who has been on bed rest for the past month?
- A. Calf swelling
- B. Elevated blood pressure
- C. Decreased urine output
- D. Generalized rash
Correct Answer: A
Rationale: Calf swelling is a common sign of thrombophlebitis, which is inflammation of a vein due to a blood clot. Prolonged immobility can predispose individuals to thrombophlebitis. Calf swelling occurs due to the obstruction of blood flow, causing localized edema. This condition can lead to serious complications like pulmonary embolism if not promptly addressed. Elevated blood pressure, decreased urine output, and a generalized rash are not typically associated with thrombophlebitis. Elevated blood pressure may be linked to other conditions like hypertension, decreased urine output to kidney dysfunction, and a generalized rash to allergic reactions or skin conditions. Therefore, in a client on bed rest, calf swelling should raise suspicion of thrombophlebitis and prompt further evaluation and intervention.
A nurse is preparing an education program for staff about advocacy. What information should the nurse include?
- A. Advocacy ensures clients' safety, health, and rights.
- B. Advocacy involves only supporting client complaints.
- C. Advocacy means making all decisions for the client.
- D. Advocacy is not part of nursing responsibilities.
Correct Answer: A
Rationale: The correct answer is A. Advocacy in nursing involves ensuring clients' safety, health, and rights. Nurses advocate for their clients by promoting autonomy, informed decision-making, and protecting their rights. Choice B is incorrect because advocacy goes beyond just supporting client complaints; it encompasses a broader scope of ensuring holistic care and well-being. Choice C is incorrect as advocacy does not mean making all decisions for the client but rather empowering them to make informed choices. Choice D is incorrect as advocacy is a crucial component of nursing responsibilities, as it involves standing up for clients' best interests and ensuring their rights are respected.
A home health nurse who has attended a training session for the therapeutic use of aromatherapy with essential oils is planning to use this modality with some of her clients. For which of the following clients should the nurse consult the provider before using this complementary therapy?
- A. A client who has asthma.
- B. A client who has diabetes.
- C. A client who has hypertension.
- D. A client who has a history of depression.
Correct Answer: A
Rationale: The correct answer is A: a client who has asthma. Essential oils have the potential to trigger asthma symptoms due to their strong scents and chemical components. Consulting with the healthcare provider is crucial before using aromatherapy with essential oils to ensure the safety and well-being of the client with asthma. Choices B, C, and D do not pose immediate risks with aromatherapy use, making them less of a priority for consultation compared to asthma. Clients with diabetes, hypertension, or depression do not have the same immediate risks associated with the use of aromatherapy as clients with asthma. However, it is still advisable for the nurse to be aware of any potential interactions or contraindications with these conditions and consult with the provider if needed.
The healthcare provider is assessing a client with a history of congestive heart failure. Which assessment finding would be most concerning?
- A. Shortness of breath on exertion
- B. Weight gain of 2 pounds in a week
- C. Orthopnea
- D. Crackles in the lungs
Correct Answer: D
Rationale: Crackles in the lungs are concerning because they indicate pulmonary congestion, a serious complication of congestive heart failure. The presence of crackles suggests fluid accumulation in the lungs, requiring immediate attention to prevent respiratory distress and worsening heart failure. While shortness of breath on exertion, weight gain, and orthopnea are common signs and symptoms of heart failure, crackles specifically point to acute pulmonary edema or worsening congestion, making them the most concerning finding in this scenario.
