Which of the following conditions most commonly causes acute glomerulonephritis?

Correct Answer: B

Rationale: Acute glomerulonephritis is most commonly caused by the immune response to a prior upper respiratory infection with group A Streptococcus. Glomerular inflammation occurs about 10-14 days after the infection, resulting in scant, dark urine and retention of body fluid. Periorbital edema and hypertension are common signs at diagnosis.

Correct Answer: B

Rationale: During a grand mal seizure, the client is at risk of injury due to severe, involuntary muscle spasms and contractions. It is crucial for the nurse to avoid restraining the client or inserting objects into their mouth, as these actions may lead to further harm. Placing the client on their side can help facilitate the drainage of oral secretions and assist in maintaining an open airway, reducing the risk of aspiration. Restraint should be avoided as it can exacerbate muscle contractions and increase the risk of injury. Placing pillows around the client may not provide adequate support or protection during the seizure, making it a less effective intervention compared to positioning the client on their side.

Correct Answer: A

Rationale: Telemetry is used to monitor the cardiac rhythms of clients with potentially unstable conditions or those rhythms that affect activities. Clients with syncope potentially related to cardiac dysrhythmia require continuous monitoring to detect any potential life-threatening dysrhythmias. Unstable angina can be monitored in a telemetry unit, but syncope with potential cardiac causes takes precedence. Clients with sinus rhythm and PVCs may not necessitate telemetry unless there are further indications of instability. A client who had a myocardial infarction 6 hours ago is typically monitored in an intensive care unit rather than a telemetry unit.

Correct Answer: B

Rationale: A client experiencing an anaphylactic reaction will likely present with rash or hives, swelling of the lips, face, or tongue, hypotension, or dyspnea. In this scenario, the client is showing signs of anaphylaxis with dyspnea, chest tightness, hives, hypotension, and swelling of the lips and tongue. The next appropriate action would be to administer 0.3 mg of 1:1000 epinephrine intramuscularly. Epinephrine helps relax the muscles of the airway, improve breathing, and increase oxygenation, which is crucial in managing anaphylaxis. Starting an IV and administering fluids can be important but not the immediate priority. Diphenhydramine may be used as an adjunct therapy but should not delay the administration of epinephrine in the acute phase of anaphylaxis. Monitoring the client without providing immediate treatment can lead to a worsening of the anaphylactic reaction, potentially resulting in a life-threatening situation.

Correct Answer: C

Rationale: In this scenario, the client's presentation of coughing up rust-colored sputum, increased respiratory rate, expiratory grunting, and coarse crackles on lung auscultation suggests the development of pneumonia. Pneumonia is characterized by lung tissue inflammation or infection, often caused by various organisms. Symptoms may include productive cough, dyspnea, and abnormal breath sounds. Tuberculosis (Choice A) typically presents with a chronic cough, weight loss, and night sweats and is less likely in this acute post-operative setting. Pulmonary edema (Choice B) is characterized by pink, frothy sputum, crackles throughout the lungs, and typically occurs in the context of heart failure. Histoplasmosis (Choice D) is a fungal infection that usually presents with flu-like symptoms and is less likely to manifest with the specific respiratory findings described in this case.
