The nurse is teaching a patient newly diagnosed with AIDS about complications of the disease. Which of the following is the most common opportunistic infection in AIDS?
- A. Pneumocystis carinii pneumonia
- B. Toxoplasmosis
- C. Candidiasis
- D. Mycoplasma pneumoniae
Correct Answer: A
Rationale: Pneumocystis carinii pneumonia (PCP) is the most common opportunistic infection in individuals with AIDS. PCP is caused by a fungus called Pneumocystis jirovecii (formerly known as Pneumocystis carinii). Patients with AIDS have compromised immune systems, making them susceptible to opportunistic infections like PCP. This infection can be life-threatening if not treated promptly with appropriate antibiotics. Symptoms of PCP include fever, cough, and difficulty breathing. Early recognition and treatment of PCP are crucial in patients with AIDS to prevent severe complications.

What is the causative agent in HIV/AIDS?
- A. trichomonas vaginalis
- B. Treponema pallidum
- C. Human, T-cell lymphotrophio virus
- D. Chlamydia tranchomatis
Correct Answer: C
Rationale: The causative agent of HIV/AIDS is the Human Immunodeficiency Virus (HIV). HIV infects and kills the immune system's CD4 T cells, weakening the immune system and making the body more susceptible to infections and certain cancers. The virus is primarily transmitted through sexual contact, exposure to infected blood, sharing needles, and from mother to child during childbirth or breastfeeding. Trichomonas vaginalis, Treponema pallidum, and Chlamydia trachomatis are all different microorganisms that are not responsible for causing HIV/AIDS.
When caring for a client, whose being treated for hyperthyroidism, it's important to:
- A. Provide extra blankets and clothing to keep the client warm.
- B. Monitor the client for signs of restlessness, sweating and excessive weight loss during thyroid replacement therapy.
- C. Balance the client's periods of activity and rest.
- D. Encourage the client to be active to prevent constipation.
Correct Answer: B
Rationale: When caring for a client with hyperthyroidism, it is important to monitor the client for signs of restlessness, sweating, and excessive weight loss during thyroid replacement therapy. Treatment for hyperthyroidism often involves thyroid replacement therapy to restore the balance of thyroid hormones in the body. Monitoring for signs and symptoms of overmedication or undermedication is crucial to ensure the client's health and well-being. Restlessness, sweating, and weight loss can be indicators of an imbalance in thyroid hormone levels and may require adjustments in medication dosage. Regular monitoring and communication with healthcare providers are essential in managing the client's condition effectively.
The nurse is examining an infant for hip placement and has abducted her flexed legs. The nurse should next:
- A. Rotate the hips.
- B. Extend the legs.
- C. Listen for a "click."
- D. Palpate the hips for a mass.
Correct Answer: C
Rationale: In this scenario, the nurse is performing Ortolani's maneuver, which is used to assess for developmental dysplasia of the hip (DDH) in infants. After abducting the infant's flexed legs, the nurse should then listen for a "click" that may indicate hip instability. A positive click suggests subluxation of the femoral head and may indicate the presence of DDH. It is important for the nurse to recognize this finding promptly and report it to the healthcare provider for further evaluation and management. Rotation of the hips, extending the legs, and palpating for a mass are not the appropriate next steps in this specific assessment for DDH.
