Question 1 of 9
Deaths have occurred when potassium chloride has been used incorrectly to flush a lock or central venous catheter. Which of the ff precautions should a nurse take to minimize this risk?
Correct Answer: C
Rationale: Step 1: Reading labels carefully on vials containing flush solutions for locks is crucial to ensure the correct solution is being used. Step 2: Potassium chloride should not be used to flush locks as it can be fatal if administered incorrectly. Step 3: By carefully reading labels, the nurse can verify that the correct solution is being used, thus minimizing the risk of using potassium chloride. Summary: - Choice A is incorrect as using a dilute form of potassium chloride does not address the issue of incorrect administration. - Choice B is incorrect as warming the solution does not prevent the risk associated with using potassium chloride. - Choice D is incorrect as replacing locks does not address the root cause of the issue, which is improper administration.
Question 2 of 9
Which of the following would the nurse evaluate as laboratory data that support the occurrence of AIDS?
Correct Answer: D
Rationale: The correct answer is D: 200 CD4+ cells. In AIDS, the immune system is severely compromised, leading to a decrease in CD4+ T cells. A CD4+ count below 200 cells/mm3 is a key indicator of AIDS, as it signifies advanced immunodeficiency. Choices A, B, and C all have CD4+ cell counts above 200, which would not support the occurrence of AIDS. Therefore, the nurse would evaluate a CD4+ count of 200 cells as laboratory data that support the occurrence of AIDS.
Question 3 of 9
A client has had heavy menstrual bleeding for 6 months. Her gynecologist diagnoses microcytic hypochromic anemia and prescribes ferrous sulfate (Feosol), 300mg PO daily. Before initiating iron therapy, the nurse reviews the client’s medical history. Which condition would contraindicate the use of ferrous sulfate?
Correct Answer: B
Rationale: The correct answer is B: Ulcerative colitis. Iron therapy can exacerbate gastrointestinal issues, including ulcerative colitis due to its potential to cause irritation and inflammation in the digestive tract. This can lead to worsening symptoms and complications for the client. A: Pregnancy is not a contraindication for iron therapy; in fact, it is commonly prescribed during pregnancy to prevent or treat anemia. C: Asthma is not a contraindication for iron therapy as it does not directly interact with asthma or its treatment. D: Severely impaired liver function is not a direct contraindication for iron therapy, although caution may be needed in such cases due to iron metabolism being affected by liver function.
Question 4 of 9
The nurse is teaching a client who suspects that she has a lump in her breast. The nurse instructs the client that a diagnosis of breast cancer is confirmed by:
Correct Answer: B
Rationale: The correct answer is B: Fine needle aspiration. This is because fine needle aspiration involves extracting cells from the lump in the breast for examination under a microscope to determine if they are cancerous. This procedure provides a definitive diagnosis of breast cancer. Breast self-examination (A) is a screening tool for detecting lumps but does not confirm a diagnosis. Mammography (C) is used for screening and detecting abnormalities but requires further testing for confirmation. Chest x-ray (D) is not useful for diagnosing breast cancer.
Question 5 of 9
An adult had a total thyroidectomy. Which statement by the client demonstrates to the nurse an adequate understanding of long term care?
Correct Answer: A
Rationale: The correct answer is A because after a total thyroidectomy, the client will no longer produce thyroid hormones, necessitating lifelong replacement therapy. This statement shows an understanding of the need for ongoing medication to maintain thyroid function. Choice B is incorrect as the client had a total thyroidectomy, so there is no risk of hyperthyroidism recurrence. Choice C is incorrect as the client will need ongoing care and monitoring for thyroid function. Choice D is incorrect as increasing caloric intake is not a necessary long-term care measure after a thyroidectomy.
Question 6 of 9
To treat cervical cancer, a client has had an applicator of radioactive material placed in the vagina. Which observation by the nurse indicates a radiation hazard?
Correct Answer: B
Rationale: The correct answer is B because maintaining the head of the bed at a 30-degree angle can cause the radioactive material to shift within the client's body, increasing the risk of radiation exposure. This position should be avoided to prevent displacement of the applicator. A: Strict bed rest is appropriate to minimize movement and dislodgement of the applicator, ensuring proper treatment delivery. C: Providing a bed bath does not pose a radiation hazard as long as proper precautions are taken. D: Checking the applicator's position every 4 hours is essential for monitoring and ensuring it remains in place to deliver the intended treatment.
Question 7 of 9
A nurse is providing education to a patient about self-administering subcutaneous injections. The patient demonstrates the self-injection. Which type of indicator did the nurse evaluate?
Correct Answer: B
Rationale: The correct answer is B: Health behavior. Evaluating the patient's demonstration of self-injection assesses their ability to perform a specific health-related action. This choice focuses on the patient's actions and behaviors related to their health, aligning with the scenario provided. Choice A: Health status is incorrect because it refers to the patient's current physical condition, not their ability to perform a specific health action. Choice C: Psychological self-control is incorrect as it pertains to the patient's ability to regulate their emotions and impulses, not their ability to self-administer injections. Choice D: Health service utilization is incorrect as it relates to the frequency and pattern of healthcare services used by the patient, not their ability to perform a specific health behavior.
Question 8 of 9
Then the drug is stopped. When should treatment resume?
Correct Answer: A
Rationale: The correct answer is A because the drug should be resumed when the WBC count falls to 5,000mm3 to ensure the client's safety and efficacy of treatment. This criterion indicates that the client's immune system has recovered sufficiently to tolerate the drug. Choices B, C, and D are incorrect because they do not directly correlate with the client's immune system recovery, which is crucial for drug tolerance. Choice B focuses on the rise in WBC count, not the fall to a specific level. Choice C is related to a cosmetic side effect, not clinical readiness. Choice D is unrelated to immune system recovery.
Question 9 of 9
When the patient’s signature is witnessed by the nurse on the surgical consent, which of the following does the nurse’s signature indicate?
Correct Answer: D
Rationale: The correct answer is D because the nurse's signature indicates that they verified the patient's signature on the consent form. This step ensures that the patient has signed the document willingly. Choice A is incorrect because the nurse doesn't obtain informed consent, that's the responsibility of the physician. Choice B is incorrect because nurses do not provide informed consent. Choice C is incorrect as the nurse witnessing the signature doesn't imply they answered all surgical procedure questions.
