A client has entered disseminated intravascular coagulation (DIC) after becoming extremely ill after surgery. Which of the following laboratory findings would the nurse expect to see with this client?
- A. Elevated fibrinogen level
- B. Prolonged PT
- C. Elevated platelet count
- D. Depressed d-dimer level
Correct Answer: B
Rationale: In disseminated intravascular coagulation (DIC), a client experiences widespread clotting throughout the body, leading to the depletion of clotting factors and platelets. A prolonged prothrombin time (PT) is a common finding in DIC. The PT measures the extrinsic pathway of the clotting cascade and reflects how quickly blood can clot. In DIC, the consumption of clotting factors results in a prolonged PT, indicating impaired clotting ability. Elevated fibrinogen levels (Choice A) are typically seen in the early stages of DIC due to the body's attempt to compensate for clot breakdown. Elevated platelet count (Choice C) is not a typical finding in DIC as platelets are consumed during the widespread clotting. A depressed d-dimer level (Choice D) is also not expected in DIC as d-dimer levels are elevated due to the breakdown of fibrin clots. Therefore, the correct answer is a prolonged PT.

A client is receiving education on cholesterol. Which of the following statements from the client indicates the need for further teaching?
- A. I would like my HDL levels to be over 50.
- B. It is better for me to have high HDL levels and low LDL levels.
- C. It is better for me to have high LDL levels and low HDL levels.
- D. My goal is to get my total cholesterol below 200.
Correct Answer: C
Rationale: The correct answer is, 'It is better for me to have high LDL levels and low HDL levels.' This statement indicates a need for further teaching because high LDL levels contribute to atherosclerosis, while high HDL levels can protect against heart disease. The client should understand the importance of lowering LDL levels and increasing HDL levels to maintain good heart health. Choice A is correct as desiring HDL levels over 50 is a positive goal. Choice B is correct as it reflects the ideal scenario of high HDL and low LDL levels. Choice D is correct as a total cholesterol below 200 is a common goal for heart health. Therefore, Choice C is incorrect as it suggests an opposite and unhealthy relationship between LDL and HDL levels.
A client with asthma is being admitted for breathing difficulties. His arterial blood gas results are pH 7.26, PCO2 49, PaO2 90, and HCO3- 21. Which of the following best describes this condition?
- A. Uncompensated respiratory acidosis
- B. Compensated respiratory alkalosis
- C. Uncompensated metabolic acidosis
- D. Compensated metabolic alkalosis
Correct Answer: A
Rationale: In this case, the client's arterial blood gas results show a pH of 7.26 and a PCO2 of 49, both of which are abnormal. A pH below the normal range of 7.35-7.45 indicates acidosis. The elevated PCO2 of 49 mmHg suggests respiratory acidosis as the primary issue. The normal range for PCO2 is 35-45 mmHg, so a value of 49 indicates the retention of excess CO2, leading to acidosis. The low HCO3- level of 21 also supports the presence of metabolic acidosis; however, the primary abnormality is respiratory, making this an uncompensated respiratory acidosis. Therefore, the correct answer is 'Uncompensated respiratory acidosis.'
Choice B, 'Compensated respiratory alkalosis,' is incorrect because the client's pH is acidic, not alkalotic. Additionally, there is no compensation occurring for the primary respiratory acidosis indicated by the elevated PCO2.
Choice C, 'Uncompensated metabolic acidosis,' is incorrect because while the HCO3- level is low, the primary issue indicated by the elevated PCO2 is respiratory acidosis.
Choice D, 'Compensated metabolic alkalosis,' is incorrect since the arterial blood gas results do not support a metabolic alkalosis. The low HCO3- level would typically be seen in metabolic acidosis, but in this case, the primary issue is respiratory acidosis.
A client is preparing to undergo a cystoscopy for stones. Which of the following statements indicates that the client understands the procedure?
- A. I better drink a lot of fluid now because I won't be able to after the test.
- B. I will probably see a little blood when I urinate.
- C. I will be able to go home after 3 days in the hospital.
- D. I won't need any pain medicine; this probably will not hurt.
Correct Answer: B
Rationale: The correct answer is, 'I will probably see a little blood when I urinate.' During a cystoscopy, a scope is inserted into the client's bladder to inspect structures or remove objects like stones. This procedure is usually performed under local or general anesthesia. It is common for clients to experience a small amount of blood in their urine (hematuria) or have pink-colored urine after the procedure. The other choices are incorrect because drinking a lot of fluid before the test, staying in the hospital for 3 days, and assuming no pain will be experienced are not accurate statements related to a cystoscopy procedure.
Which of the following situations warrants a measurement for orthostatic hypotension?
- A. A 36-year-old male with a spinal injury
- B. An 86-year-old female with significantly altered mental status
- C. A 58-year-old female with near-syncope
- D. A 41-year-old male with acute deep vein thrombosis
Correct Answer: C
Rationale: The correct answer is a 58-year-old female with near-syncope. Orthostatic hypotension is a drop in blood pressure of greater than 20 mmHg systolic when moving from a sitting or lying position to standing. Patients at higher risk include those with syncope or near-syncope, symptomatic hypovolemia, and those prone to falls. The other choices are less likely to present with orthostatic hypotension. A spinal injury, altered mental status, and acute deep vein thrombosis are not directly associated with the immediate need for orthostatic hypotension measurement.
Which of the following conditions may cause an increased respiratory rate?
- A. Stooped posture
- B. Narcotic analgesics
- C. Injury to the brain stem
- D. Anemia
Correct Answer: D
Rationale: Anemia can lead to an increased respiratory rate. In anemia, there are decreased levels of hemoglobin in red blood cells, which are responsible for carrying oxygen to the body's tissues. To compensate for the reduced oxygen-carrying capacity, the body increases the respiratory rate to bring in more oxygen.
Stooped posture (Choice A) is not directly related to an increased respiratory rate. Narcotic analgesics (Choice B) are more likely to cause a decreased respiratory rate due to their central nervous system depressant effects. Injury to the brain stem (Choice C) can affect respiratory function but may not necessarily lead to an increased respiratory rate.
