The most common buffer system in the body is the:
- A. Plasma protein buffer system
- B. Phosphate buffer system
- C. Hemoglobin buffer system
- D. Bicarbonate-carbonic system
Correct Answer: D
Rationale: The most common buffer system in the body is the bicarbonate-carbonic system. This system plays a crucial role in maintaining the pH balance in the blood. The bicarbonate ion (HCO3-) acts as a weak base, while carbonic acid (H2CO3) acts as a weak acid. The balance between these two components helps to regulate the pH of the blood.
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.
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.
