Extract:
Question 1 of 5
A nurse is reviewing the EKG strip of a client who has prolonged vomiting. Which of the following abnormalities on the client's EKG should the nurse interpret as a sign of hypokalemia?
Correct Answer: A
Rationale: The correct answer is A: Abnormally prominent U wave. In hypokalemia, low potassium levels can lead to U wave prominence on an EKG. The U wave becomes more visible and prominent due to delayed repolarization of the Purkinje fibers. This is a classic EKG finding in hypokalemia. Tachycardia (choice
B) is a non-specific finding and can be caused by various conditions. Flattened P wave (choice
C) is seen in hyperkalemia, not hypokalemia. Prolonged PR interval (choice
D) is more indicative of first-degree heart block or other conduction abnormalities, not specifically hypokalemia.
Question 2 of 5
During a routine physical examination, a nurse observes a 1-cm (0.4-in) lesion on a client's chest. The lesion is raised and flesh-colored with pearly white borders. The nurse should recognize that this finding is suggestive of which of the following types of skin cancer?
Correct Answer: C
Rationale: The correct answer is C: Basal cell carcinoma. Basal cell carcinoma typically presents as a raised, flesh-colored lesion with pearly white borders. This type of skin cancer is the most common and is usually slow-growing with low metastatic potential. It is often found on sun-exposed areas such as the face, neck, and chest. Melanoma (
A) is characterized by asymmetry, irregular borders, varied color, and a diameter larger than 6mm. Squamous cell carcinoma (
B) is usually a firm, red nodule or a flat lesion with a scaly crust. Kaposi's sarcoma (
D) typically presents as purple or blue-black patches or nodules on the skin.
Question 3 of 5
A nurse is teaching a client who has been taking prednisone to treat asthma and has a new prescription to discontinue the medication. The nurse should explain to the client to reduce the dose gradually to prevent which of the following adverse effects?
Correct Answer: D
Rationale: The correct answer is D: Adrenocortical insufficiency. Gradually reducing prednisone dose is important as prednisone suppresses the body's natural production of cortisol. Abrupt discontinuation can lead to adrenal insufficiency due to the sudden decrease in cortisol levels. This can result in symptoms such as fatigue, weakness, weight loss, and hypotension. Osteoporosis (
A) is a long-term side effect of prednisone but not a concern with dose reduction. Hypoglycemia (
B) and Hyperkalemia (
C) are not typically associated with prednisone withdrawal.
Question 4 of 5
A nurse is planning a presentation about HIV for a church-based group. Which of the following information about HIV transmission should the nurse include?
Correct Answer: A
Rationale: The correct answer is A because HIV is primarily transmitted through direct contact with infected body fluids such as blood, semen, vaginal fluids, and breast milk. This includes activities like unprotected sexual intercourse, sharing needles, and mother-to-child transmission during childbirth or breastfeeding. Casual contact (choice
B) is not a common mode of transmission, and HIV is not transmitted through airborne droplets (choice
C). While sexual contact is a significant mode of transmission, HIV can also be transmitted through other means involving infected body fluids. Thus, option D is incorrect as it is too limiting.
Question 5 of 5
A nurse cares for a client on ethambutol therapy for tuberculosis. What should be monitored?
Correct Answer: B
Rationale: The correct answer is B: Visual acuity. Ethambutol can cause optic neuritis, leading to visual disturbances. Monitoring visual acuity is crucial to detect any changes early.
Incorrect choices:
A: Hearing loss is associated with other medications for TB, not ethambutol.
C: Liver function is not typically affected by ethambutol.
D: Blood glucose is not directly impacted by ethambutol therapy.
In summary, monitoring visual acuity is essential due to the potential optic nerve toxicity of ethambutol, making it the most relevant parameter to monitor in this case.
