A 20-year-old obese female client is preparing to have gastric bypass surgery for weight loss. She says to the nurse, "I need this surgery because nothing else I have done has helped me to lose weight."? Which response by the nurse is most appropriate?
- A. "If you eat less, you can save some money."?
- B. "Exercise is a healthier way to lose weight."?
- C. "You should try the Atkins diet first."?
- D. "I respect your decision to choose surgery."?
Correct Answer: D
Rationale: The most appropriate response by the nurse is to show respect and empathy towards the client's decision. Option D acknowledges the client's autonomy and decision-making process, fostering a therapeutic relationship. Options A, B, and C are insensitive and unprofessional. Option A implies a financial incentive for weight loss, which can be perceived as disrespectful and trivializing the client's concerns. Option B suggests an alternative method without considering the client's reasons for choosing surgery, potentially invalidating her experiences. Option C recommends a specific diet without addressing the client's concerns or choices, neglecting her autonomy in decision-making.

When assessing a client in the Emergency Department whose membranes have ruptured, the nurse notes that the fluid is a greenish color. What is the cause of this greenish coloration?
- A. blood
- B. meconium
- C. hydramnios
- D. caput
Correct Answer: B
Rationale: The correct answer is B: meconium. Greenish amniotic fluid passed when the fetus is in a cephalic (head) presentation might indicate fetal distress. A fetus in the breech presentation passes meconium due to compression on the intestinal tract. Choice A, blood, is incorrect as blood in the amniotic fluid would present as a different color. Choice C, hydramnios, refers to an excess of amniotic fluid and would not cause the greenish coloration. Choice D, caput, is swelling of a newborn's scalp and is not related to the color of the amniotic fluid.
Assessment of the client with an arteriovenous fistula for hemodialysis should include:
- A. inspection for visible pulsations.
- B. palpation of thrill.
- C. percussion for dullness.
- D. auscultation of blood pressure.
Correct Answer: B
Rationale: The correct answer is to palpate for a thrill. A thrill should be present in a functioning arteriovenous fistula (AVF) and indicates good blood flow. The client should be educated to check for this sensation daily at home to monitor the AVF's patency. Visible pulsations are not typically observed in an AVF. Percussion for dullness does not provide relevant information about the AVF. Auscultation of blood pressure is not a standard practice in assessing an AVF. However, auscultation of the AVF for a bruit, a sound indicating turbulent blood flow, is crucial in evaluating the AVF's patency.
A nurse is caring for a client with an elevated urine osmolarity. The nurse should assess the client for:
- A. fluid volume excess.
- B. hyperkalemia.
- C. hypercalcemia.
- D. fluid volume deficit.
Correct Answer: D
Rationale: Elevated urine osmolarity indicates that the urine is concentrated, suggesting the body is trying to conserve water. This commonly occurs in conditions like dehydration or fluid volume deficit. Assessing the client for fluid volume excess, hyperkalemia, or hypercalcemia would not be the priority in this situation. Therefore, the correct answer is to assess the client for fluid volume deficit. Fluid volume excess is characterized by decreased urine osmolarity, while hyperkalemia and hypercalcemia are related to electrolyte imbalances and would not directly cause elevated urine osmolarity.
What is a chemical reaction between drugs before their administration or absorption known as?
- A. a drug incompatibility
- B. a side effect
- C. an adverse event
- D. an allergic response
Correct Answer: A
Rationale: A chemical reaction between drugs before their administration or absorption is termed a drug incompatibility. This phenomenon commonly happens when drug solutions are mixed before intravenous administration, but it can also occur with orally administered drugs. Choices B, C, and D are incorrect because side effects, adverse events, and allergic responses occur after the administration and absorption of drugs, not prior to it.
The chemotherapeutic agent 5-fluorouracil (5-FU) is ordered for a client as an adjunct measure to surgery. Which statement about chemotherapy is true?
- A. It is a local treatment affecting only tumor cells.
- B. It is a systemic treatment affecting both tumor and normal cells.
- C. It has not yet been proven an effective treatment for cancer.
- D. It is often the drug of choice because it causes few, if any, side effects.
Correct Answer: B
Rationale: The correct answer is that chemotherapy is a systemic treatment affecting both tumor and normal cells. 5-FU, as an antimetabolic drug, inhibits DNA synthesis and interferes with cell replication systemically. It affects all rapidly growing cells, including malignant and normal ones. This drug is used as adjuvant therapy for various cancers. Choice A is incorrect because chemotherapy affects both tumor and normal cells, not just tumor cells. Choice C is incorrect as chemotherapy has been proven effective in treating cancer. Choice D is incorrect because chemotherapy often causes side effects like bone marrow depression, anorexia, stomatitis, nausea, and vomiting.
