Correct Answer: C

Rationale: In a postpartum client who presents with severe abdominal pain, nausea, and vomiting, it is crucial to assess for signs of peritonitis or surgical abdomen. These signs may include rebound tenderness, guarding, rigidity, and fever. Peritonitis is a serious condition that may require immediate surgical intervention. Administering antiemetic medication, encouraging clear fluids, or providing a heating pad may not address the underlying cause of the symptoms and delay appropriate treatment. Assessing for signs of peritonitis or surgical abdomen is crucial for prompt identification and management of the client's condition.

Correct Answer: B

Rationale: The correct answer is B: Psoriasis. Psoriasis is characterized by pruritic, erythematous patches with silvery scales, commonly found on the elbows, knees, and scalp. This presentation matches the patient's symptoms. Eczema (choice A) typically presents with red, inflamed, and itchy skin patches. Pityriasis rosea (choice C) manifests as a herald patch followed by smaller scaly patches in a "Christmas tree" distribution. Seborrheic dermatitis (choice D) involves oily, yellowish, scaly patches mainly on the scalp, face, and ears, and does not typically present with silvery scales.

Correct Answer: C

Rationale: The most appropriate nursing action in this situation is to notify the healthcare provider immediately. The client presenting with persistent, severe perineal pain and swelling, along with ecchymosis and tenderness of the perineum, could be indicative of complications such as a perineal hematoma. A perineal hematoma is a collection of blood in the perineal tissues and can be a serious postpartum complication requiring prompt medical attention. Therefore, it is crucial to alert the healthcare provider so that appropriate assessment, management, and treatment can be initiated promptly. Applying ice packs or encouraging the client to sit on a donut cushion may not be sufficient in this situation, and administering additional analgesic medication should be done only after the healthcare provider has assessed and determined the cause of the symptoms.

Correct Answer: C

Rationale: The correct answer is C: Nasal polyps. Nasal polyps are benign growths that form in the nasal cavity and sinuses, leading to symptoms such as chronic nasal congestion, hyposmia, and anosmia. The presence of polypoid masses seen on nasal endoscopy is characteristic of nasal polyps. Rationale: 1. Chronic nasal congestion, hyposmia, and anosmia are common symptoms of nasal polyps. 2. Nasal endoscopy revealing polypoid masses confirms the presence of nasal polyps. 3. Allergic rhinitis may cause nasal congestion but does not typically present with polypoid masses. 4. Chronic sinusitis can cause nasal congestion but is usually associated with inflammation of the sinuses, not just polypoid masses. 5. A deviated nasal septum can lead to nasal congestion but does not typically cause polypoid masses obstructing the nasal cavity and sinuses.

Correct Answer: C

Rationale: The correct answer is C: Group A beta-hemolytic Streptococcus (GAS). GAS is the most likely organism responsible for this presentation, known as acute bacterial tonsillitis. GAS commonly causes symptoms such as throat pain, odynophagia, fever, tonsillar enlargement with exudates, and cervical lymphadenopathy. Streptococcal pharyngitis is a common bacterial infection of the throat caused by GAS. The other options are less likely as Streptococcus pneumoniae typically causes pneumonia and Haemophilus influenzae is associated with respiratory tract infections. Epstein-Barr virus (EBV) commonly causes infectious mononucleosis, which presents with different symptoms than those described in the question.
