1. Which of the following lab values would indicate symptomatic AIDS in the medical chart? (T4 cell count per deciliter)
- A. Greater than 1000 cells per deciliter
- B. Less than 500 cells per deciliter
- C. Greater than 2000 cells per deciliter
- D. Less than 200 cells per deciliter
Correct answer: D
Rationale: A T4 cell count of less than 200 cells per deciliter indicates symptomatic AIDS. This severe depletion of T4 cells signifies advanced HIV infection and a significantly compromised immune system. Choices A, B, and C are incorrect because T4 cell counts above 2000, above 1000, or below 500 cells per deciliter, respectively, are not indicative of symptomatic AIDS.
2. The nurse is caring for a burn victim with a skin graft to the hand. The area is pale and mottled but has good capillary refill. What is the nurse's best action at this time?
- A. Warm the room
- B. Submerge the hand in warm water
- C. Order a K pad and apply to hand
- D. Have the client exercise the fingers to increase blood flow
Correct answer: A
Rationale: The correct action for the nurse to take when caring for a burn victim with a skin graft to the hand, exhibiting pale and mottled skin but good capillary refill, is to warm the room. By warming the room, the nurse helps promote circulation and maintain a conducive environment for healing. Submerging the hand in warm water can pose a risk of injury or infection to the graft site. Ordering a K pad and applying it to the hand may not be necessary at this time and could potentially cause harm. Having the client exercise the fingers to increase blood flow is also not recommended as it may interfere with the healing process of the skin graft.
3. What is the best lab test to diagnose disseminated intravascular coagulation (DIC)?
- A. platelet count
- B. prothrombin time (PT)
- C. partial thromboplastin time (PTT)
- D. D-dimer
Correct answer: D
Rationale: The best lab test to diagnose disseminated intravascular coagulation (DIC) is the D-dimer test. In DIC, numerous small clots form throughout the body and are rapidly broken down. D-dimer measures a specific fibrin split product and is the most specific test for DIC. Platelet count (Choice A) is decreased in DIC due to consumption, but it is not specific for diagnosing DIC. Prothrombin time (PT - Choice B) and partial thromboplastin time (PTT - Choice C) are both elevated in DIC because clotting factors have been used up, but they are not specific for DIC as they can be elevated in other conditions as well.
4. One drug can alter the absorption of another drug. One drug increases intestinal motility. Which effect does this have on the second drug?
- A. None; absorption of the second drug is not affected.
- B. The increased gut motility decreases the absorption of the second drug.
- C. The absorption of the second drug cannot be predicted.
- D. Less of the second drug is absorbed.
Correct answer: D
Rationale: When one drug increases intestinal motility, it accelerates the movement of the second drug through the system. Since most oral medications are absorbed in the intestine, the faster transit time decreases the absorption of the second drug. Therefore, less of the second drug is absorbed. Choice A is incorrect because the increased gut motility does affect the absorption of the second drug. Choice C is incorrect as the effect of increased intestinal motility on drug absorption can be predicted based on pharmacokinetic principles. Choice B is incorrect as increased gut motility would not increase but decrease the absorption of the second drug.
5. A patient 3 hours post-op from a hysterectomy is complaining of intense pain at the incision site. When assessing the patient, the nurse notes a BP of 169/93, pulse 145 bpm, and regular. What action should the nurse take?
- A. Reassure the patient that pain is normal following surgery.
- B. Administer prn Nifedipine and assess the client's response.
- C. Administer prn Meperidine HCL and assess the client's response.
- D. Recheck BP and pulse rate every 20 minutes for the next hour.
Correct answer: C
Rationale: The correct action for the nurse to take in this situation is to administer prn Meperidine HCL and assess the client's response. A BP of 169/93 and a pulse of 145 bpm indicate pain-related hypertension and sinus tachycardia, which are physiological responses to pain. Treating the cause of the increased pulse rate requires pain medication. Reassuring the patient about normal post-surgery pain is important, but addressing the physiological responses to pain is a priority. Administering Nifedipine, a calcium channel blocker, is not indicated for pain management but for hypertension. Rechecking the BP and pulse rate without addressing the pain directly does not address the underlying issue causing the elevated vital signs.
