1. Blood for arterial blood gas determinations is drawn from a client with pneumonia, and testing reveals a pH of 7.45, PCO2 of 30 mm Hg, and HCO3 of 19 mEq/L. The nurse interprets these results as indicative of:

Correct answer: B

Rationale: The correct answer is 'Compensated respiratory alkalosis.' In this case, the client's pH is within the normal range (7.35-7.45), indicating compensation. The low PCO2 (30 mm Hg) suggests respiratory alkalosis, while the low HCO3 (19 mEq/L) is also consistent with a compensatory response. Therefore, the client has a primary respiratory alkalosis that is being compensated for by metabolic acidosis. Choices A, C, and D are incorrect because they do not fit the pattern of the given blood gas values, which indicate respiratory alkalosis with metabolic compensation.

2. Which of the following lab values would be most concerning in a patient receiving heparin therapy?

Correct answer: B

Rationale: A low platelet count is most concerning in patients receiving heparin therapy due to the risk of heparin-induced thrombocytopenia. Heparin can sometimes cause a drop in platelet count, leading to a potentially serious condition where blood does not clot as it should. This can result in excessive bleeding or clot formation in blood vessels. Elevated hemoglobin levels, high potassium levels, and low sodium levels are not typically associated with heparin therapy and are less likely to cause immediate concerns or complications in this context.

3. What do crackles heard on lung auscultation indicate?

Correct answer: D

Rationale: Crackles heard on lung auscultation are caused by the popping open of small airways that are filled with fluid. This is commonly associated with conditions such as pulmonary edema, pneumonia, or heart failure. Cyanosis (Choice A) is a bluish discoloration of the skin and mucous membranes due to low oxygen levels in the blood, not directly related to crackles. Bronchospasm (Choice B) refers to the constriction of the airway smooth muscle, causing difficulty in breathing but does not typically produce crackles. Airway narrowing (Choice C) can lead to wheezing but is not directly linked to crackles heard on auscultation.

4. The nurse is caring for a client who is postoperative for a femoral head fracture repair. Which intervention(s) should the nurse plan to administer for deep vein thrombosis prophylaxis?

Correct answer: A

Rationale: The correct intervention for deep vein thrombosis prophylaxis in a postoperative client with a femoral head fracture repair is the use of pneumatic compression devices. These devices help prevent stasis in the lower extremities by promoting venous return through intermittent compression. Incentive spirometry is used to prevent respiratory complications by promoting lung expansion and clearing secretions, not for DVT prophylaxis. Assisted ambulation and calf-pump exercises are beneficial for promoting circulation and preventing DVT, but pneumatic compression devices are more effective in this specific postoperative scenario.

5. An adult client is admitted with flank pain and is diagnosed with acute pyelonephritis. What is the priority nursing action?

Correct answer: C

Rationale: The priority nursing action for a client diagnosed with acute pyelonephritis is to administer IV antibiotics as prescribed. Acute pyelonephritis is a serious kidney infection that requires prompt antibiotic therapy to prevent systemic complications and worsening of the infection. While monitoring hemoglobin and hematocrit (Choice A) is important, it is not the priority in the acute phase of infection. Encouraging turning and deep breathing (Choice B) and auscultating for bowel sounds (Choice D) are relevant aspects of care but do not take precedence over initiating antibiotic treatment to address the infection promptly.
