Correct Answer: C

Rationale: An increased respiratory rate is a sign of fluid volume deficit as the body attempts to compensate for decreased blood volume. Jugular vein distention, bradycardia, and bounding pulses are not typical findings of fluid volume deficit. Jugular vein distention is more commonly associated with fluid volume overload, bradycardia can be a sign of fluid volume excess or other issues, and bounding pulses are not typically seen in fluid volume deficit.

Correct Answer: B

Rationale: The correct answer is B: aPTT. The activated partial thromboplastin time (aPTT) is monitored to assess the therapeutic effect of heparin and to adjust the infusion rate if needed. Monitoring hemoglobin levels (choice A) is important for assessing anemia but is not specific to heparin therapy. INR (choice C) is used to monitor the effects of warfarin, not heparin. Platelet count (choice D) is important to monitor for heparin-induced thrombocytopenia, but aPTT is the primary laboratory value used to monitor heparin therapy.

Correct Answer: D

Rationale: The correct answer is D: Positive rheumatoid factor. A positive rheumatoid factor is a common laboratory finding in clients with rheumatoid arthritis, indicating an autoimmune response. Option A, increased WBC count, is not typically associated with rheumatoid arthritis. Option B, decreased hemoglobin, and option C, decreased platelet count, are not specific laboratory findings for rheumatoid arthritis.

Correct Answer: C

Rationale: The correct answer is C: Potassium 3.2 mEq/L. A potassium level of 3.2 mEq/L is below the normal range and should be monitored in clients receiving furosemide due to the risk of hypokalemia. Furosemide is a loop diuretic that can cause potassium depletion, leading to hypokalemia. Monitoring potassium levels is crucial to prevent complications such as cardiac arrhythmias. Choices A, B, and D are not directly impacted by furosemide therapy in the same way as potassium levels, making them less relevant for monitoring in this scenario.

Correct Answer: A

Rationale: The correct answer is A: 'You should eat crackers before getting out of bed.' Eating crackers before getting out of bed can help reduce nausea and vomiting during pregnancy. This recommendation helps in stabilizing blood sugar levels before fully waking up. Choice B is incorrect because ginger ale may exacerbate nausea due to its carbonation. Choice C is incorrect as lying down after eating can worsen symptoms of nausea. Choice D is incorrect as avoiding eating between meals can lead to low blood sugar levels, worsening nausea and vomiting.
