Which of the following conditions is a contraindication for performing a diagnostic peritoneal lavage?

Correct Answer: C

Rationale: Diagnostic peritoneal lavage is contraindicated in morbidly obese clients due to several reasons. Excess body fat in morbidly obese individuals makes it challenging to locate essential landmarks required for the procedure. Additionally, the equipment utilized for the lavage may not be sized appropriately to accommodate an obese individual. Furthermore, morbid obesity places undue stress on the cardiovascular and respiratory systems, increasing the risk of complications when administering anesthetic agents during the procedure. Therefore, performing a diagnostic peritoneal lavage on a morbidly obese client is not recommended. Choice A, a client who is 9 weeks pregnant, is not a contraindication for diagnostic peritoneal lavage. Pregnancy status alone does not preclude the procedure unless there are specific maternal or fetal concerns. Choice B, a client with a femur fracture, is not a contraindication for diagnostic peritoneal lavage. The presence of a femur fracture does not typically affect the ability to perform this diagnostic procedure. Choice D, a client with hypertension, is not a contraindication for diagnostic peritoneal lavage. Hypertension, while a consideration for anesthesia and surgery, does not directly impact the feasibility of performing a diagnostic peritoneal lavage.

Correct Answer: A

Rationale: When caring for a patient with severe mitral regurgitation and decreased cardiac output, assessing for mental status changes is crucial. Decreased cardiac output can lead to inadequate perfusion and oxygenation of vital organs, including the brain, resulting in hypoxia. This hypoxia can manifest as mental status changes such as confusion, restlessness, or lethargy. Therefore, monitoring mental status helps in identifying potential hypoxic states and guiding appropriate interventions. The other options are incorrect as they do not directly correlate decreased cardiac output with potential hypoxia-induced mental status changes.

Correct Answer: D

Rationale: Xerostomia, also known as dry mouth, is a common side effect of radiation therapy in the head and neck region. It occurs when the salivary glands are damaged during treatment, reducing saliva production and causing a dry sensation in the mouth. The correct answer is 'Dry mouth' (option D). Choice A, 'Cracks in the corners of the mouth,' describes angular cheilitis, a condition linked to nutritional deficiencies or candida infection. Choice B, 'Peeling skin from the tongue and gums,' is more indicative of conditions like oral thrush or mucositis. Choice C, 'Increased dental caries,' is a consequence of reduced saliva flow but does not specifically describe xerostomia.

Correct Answer: B

Rationale: The correct answer is 'My baby will need two shots soon after birth.' A baby born to a mother with hepatitis B should receive two injections soon after birth to reduce the risk of contracting the disease. Within the first 12 hours post-birth, the baby should receive the first hepatitis B vaccine and hepatitis B immune globulin (HBIG) for additional protection. Option A is incorrect because the need for a cesarean section is not directly related to the mother's hepatitis B status. Option C is incorrect as breastfeeding can be safe if managed properly. Option D is incorrect as the baby's father should also be tested for hepatitis B to prevent transmission to the newborn.

Correct Answer: D

Rationale: Phototherapy is used to treat high levels of bilirubin among infants, typically evidenced as jaundice. The nurse must position the infant carefully during this procedure to maximize the benefits of the light therapy while protecting the baby. Placing protective eyewear over the baby's eyes without covering the nose is crucial to shield the eyes from the ultraviolet light. Undressing the baby down to a diaper and hat (Choice A) is a standard practice to maximize skin exposure to the phototherapy light. Placing the baby in his mother's arms before turning on the light (Choice B) is not necessary for the preparation of the infant for phototherapy. Positioning the phototherapy light approximately 3 inches above the baby's skin (Choice C) is incorrect as the distance should be as recommended by the healthcare provider based on the manufacturer's instructions.
