A client with a diagnosis of rheumatoid arthritis is prescribed methotrexate. What is the primary action of this medication?

Correct Answer: B

Rationale: The correct answer is B: Methotrexate is an immunosuppressant that works by suppressing the immune system, thereby reducing inflammation in rheumatoid arthritis. Methotrexate does not directly increase joint lubrication (Choice A) as its primary action is on the immune system. Choices C and D are incorrect since methotrexate does not enhance bone density or stimulate cartilage regeneration. It is crucial for healthcare providers to understand the mechanism of action of medications to provide safe and effective care to patients.

Correct Answer: B

Rationale: The correct answer is B: Between 24 to 28 cm. Fundal height corresponds to the weeks of gestation, so at 26 weeks of pregnancy, the fundal height should range between 24 to 28 cm. This measurement is a quick way to assess fetal growth and amniotic fluid volume. Choice A is incorrect because fundal height may vary and not always match the exact weeks of pregnancy. Choice C, measuring above the umbilicus by two finger widths, is not a standard method for fundal height measurement. Choice D, below the xiphoid process, is too high and not relevant for assessing fundal height during pregnancy.

Correct Answer: B

Rationale: The correct answer is B: Monitor blood pressure and pulse. When a client reports feeling dizzy and light-headed when standing up, the nurse's best initial action should be to monitor the client's blood pressure and pulse. These symptoms are indicative of orthostatic hypotension, which can be confirmed by changes in blood pressure and pulse when moving from lying to standing positions. Instructing the client to sit or lie down may provide temporary relief but does not address the underlying cause. Administering an anti-dizziness medication should not be the initial action without assessing vital signs first. Increasing fluid intake is important for overall health but is not the priority in this situation where vital sign monitoring is needed to assess for orthostatic hypotension.

Correct Answer: D

Rationale: When preparing a client for discharge after a myocardial infarction, the nurse should prioritize providing comprehensive instructions. This includes educating the client about warning signs of a potential heart attack to recognize symptoms early, stressing the importance of medication adherence for optimal recovery and prevention of further cardiac events, and ensuring understanding of follow-up appointment details for ongoing monitoring and care. All these aspects are crucial in preventing complications and promoting the client's well-being. Therefore, selecting 'All of the above' as the correct answer is the most appropriate choice. Choices A, B, and C are all essential components of a holistic discharge plan for a client post-myocardial infarction.

Correct Answer: C

Rationale: The correct answer is C. An elevated blood pressure in clients with chronic kidney disease undergoing hemodialysis can indicate fluid overload or poor dialysis efficacy and should be reported immediately. This finding could lead to complications such as heart failure or pulmonary edema. Choices A, B, and D are not as critical in this situation. Decreased urine output may be expected due to the kidney disease, a weight loss of 1 kg is within an acceptable range, and the presence of a bruit over the fistula is a common finding in clients undergoing hemodialysis and does not require immediate reporting.
