Correct Answer: C

Rationale: Rhogam is administered to RH-negative mothers who have an RH-positive infant to prevent the development of anti-RH antibodies in the mother's system. Choice A (RH positive, RH positive) is incorrect because Rhogam is not used when both mother and infant are RH positive. Choice B (RH positive, RH negative) is incorrect because Rhogam is used when the mother is RH negative, not RH positive. Choice D (RH negative, RH negative) is incorrect as Rhogam is not typically needed if both mother and infant are RH negative.

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.

Correct Answer: C

Rationale: In Wilms tumor staging, stage II indicates that the tumor extends beyond the kidney but is completely resected. This means that the tumor has spread beyond the kidney but has been successfully removed. Choices A and B are incorrect because a tumor less than 3 cm in size and a tumor that did not extend beyond the kidney do not align with the characteristics of stage II Wilms tumor. Choice D is also incorrect as it describes a more advanced stage where the tumor has spread into the abdominal cavity and cannot be completely resected. Therefore, the correct answer is C, as it accurately reflects the characteristics of a stage II Wilms tumor.

Correct Answer: D

Rationale: The correct answer is 'Hemoglobin.' Hemoglobin levels are not indicative of coagulation status but are important for assessing oxygen-carrying capacity. Choices A, B, and C are all laboratory tests that assess coagulation. Partial thromboplastin time (PTT) and prothrombin time (PT) evaluate different aspects of the coagulation cascade, while platelet count is essential for assessing primary hemostasis. Therefore, in the context of evaluating coagulation, hemoglobin is not the appropriate choice.

Correct Answer: D

Rationale: A wound evisceration occurs when the edges of an abdominal wound separate, allowing the coils of the intestine to protrude outside of the body. The nurse should notify the physician at once if this occurs. While waiting for treatment, the nurse should cover the intestines with sterile gauze soaked in saline. Turning the client on his side or asking the client to take a breath and hold it are not appropriate actions in this situation. Pushing the abdominal contents back inside the wound using sterile gloves can lead to infection and is not within the nurse's scope of practice.
