A client with cancer that has metastazised to the liver is started on chemotherapy- His physician has specified divided doses of the antimetabolite. The client asks why he could take the drug in divided doses. The appropriate response is:
- A. " There really is no reason your doctor just wrote the orders that way."
- B. "This schedule will reduce the side effect of the drug."
- C. "Divided doses produce greater cytotoxic effects on the diseased cells."
- D. "Because these drugs prevent cell division, they are more effective in divided doses,"
Correct Answer: C
Rationale: The correct answer is C: "Divided doses produce greater cytotoxic effects on the diseased cells." Dividing the doses of the antimetabolite allows for more consistent levels of the drug in the bloodstream, ensuring sustained exposure to the cancer cells. This continuous exposure enhances the drug's cytotoxic effects, increasing its efficacy in targeting and destroying the diseased cells. Options A and B provide vague or incorrect information, while option D is misleading as antimetabolites do not prevent cell division, but rather disrupt DNA synthesis.

. Which of the following laboratory test results would the nurse expect to find in a client diagnosed with Hashimoto’s thyroiditis?
- A. Thyroxine (T4), 22 ug/dl; triiodothyronine (T3), 320ng/dl; thyroid-stimulating hormone
- B. (TSH) undetectable
- C. T4, 22 ug/dl; T3, 200 ng/dl; TSH 0.1 uIU/ml
- D. T4, 2 ug/dl; t3, 35 ng/dl; TSH 45 uIU/ml
Correct Answer: C
Rationale: Rationale for correct answer C: In Hashimoto's thyroiditis, an autoimmune disorder causing hypothyroidism, we expect to see normal to elevated TSH levels due to the pituitary gland stimulating the thyroid to produce more hormones. T4 and T3 levels may be within normal range or slightly decreased. Choice C reflects this pattern with T4 at 22 ug/dl, T3 at 200 ng/dl, and TSH at 0.1 uIU/ml.
Summary of why other choices are incorrect:
- Choice A: T4 and T3 levels are higher than expected in Hashimoto's thyroiditis, and TSH should be elevated, not stated as normal.
- Choice B: An undetectable TSH level is typically seen in hyperthyroidism, not hypothyroidism like Hashimoto's.
- Choice D: T4 and T3 levels are significantly lower than expected, and TSH is much higher than typically seen in Hashimoto's
A guest who is diabetic attended a bridal affair. The guest started to tremble and started to feel dizzy. Luckily a nurse is present. The best action for the nurse to take is to:
- A. encourages the guest to eat some
- B. call the guest’s personal hygiene
- C. offer the guest a peppermint
- D. give the guest a glass of orange juice
Correct Answer: D
Rationale: The correct answer is D: give the guest a glass of orange juice. This is the best action because the guest is likely experiencing hypoglycemia due to being diabetic. Orange juice contains fast-acting sugar that can quickly raise blood sugar levels. Encouraging the guest to eat some (choice A) may take longer to have an effect. Calling the guest's personal hygiene (choice B) is irrelevant to the situation. Offering the guest a peppermint (choice C) will not effectively raise blood sugar levels.
Which of the following medications should then nurse explain may cause headache as a side effect?
- A. Furosemide (Lasix)
- B. Clonidine (Catapres)
- C. Atenolol ((Tenormin)
- D. Adalat (Procardia)
Correct Answer: B
Rationale: The correct answer is B: Clonidine (Catapres). Clonidine is known to cause headache as a side effect due to its mechanism of action affecting blood pressure regulation in the brain. Furosemide (A) is a diuretic that typically causes electrolyte imbalances, not headaches. Atenolol (C) is a beta-blocker used for hypertension, which can cause fatigue but not typically headaches. Adalat (D) is a calcium channel blocker that usually causes peripheral edema, not headaches.
The NAP states that was busy and had not had a chance to tell the nurse yet. The patient begins to complain of feeling dizzy and light-headed. The blood pressure is rechecked and it has dropped even lower. In which phase of the nursing process did the nurse first make an error? NursingStoreRN
- A. Assessment
- B. Diagnosis
- C. Implementation
- D. Evaluation
Correct Answer: A
Rationale: The correct answer is A: Assessment. The nurse made an error in the assessment phase by not communicating the patient's condition promptly. Assessment involves collecting data and recognizing changes in the patient's condition. By not informing the nurse about feeling dizzy and light-headed, the nurse missed crucial information that could have indicated a deteriorating condition. The other choices are incorrect because: B: Diagnosis comes after assessment and involves analyzing data to identify the patient's problems. C: Implementation is the phase where nursing interventions are carried out based on the diagnosis. D: Evaluation is the final phase where the nurse assesses the effectiveness of interventions and outcomes.
The nurse completes a health history and physical assessment on a client who has been admitted to the hospital for surgery. What is the purpose of this initial assessment?
- A. To gather data about a specific and current health problem.
- B. To identify life-threatening problems that require immediate attention.
- C. To compare and contrast current health status to baseline data.
- D. To establish a database to identify problems and strengths.
Correct Answer: D
Rationale: The correct answer is D: To establish a database to identify problems and strengths. This initial assessment is crucial for gathering comprehensive information about the client's health status, including past medical history, current health problems, and potential risk factors. By establishing a database, the nurse can identify both existing health issues that need to be addressed and strengths that can be built upon for effective care planning. This assessment serves as the foundation for developing an individualized care plan and monitoring the client's progress throughout their hospital stay.
Explanation of other options:
A: To gather data about a specific and current health problem - While this may be part of the assessment process, the main purpose is broader in scope to establish a comprehensive database.
B: To identify life-threatening problems that require immediate attention - While identifying urgent issues is important, the initial assessment is not solely focused on life-threatening problems.
C: To compare and contrast current health status to baseline data - While comparing to baseline data is important for tracking changes, the primary purpose
