Correct Answer: D

Rationale: The correct answer is D because breast implants can hinder mammography by obscuring the view of breast tissue, making it difficult to detect abnormalities like masses. This is due to the implants blocking the x-ray machine's view. Choice A is incorrect as discomfort is not the primary reason for interference. Choice B is incorrect as breast implants are not a contraindication to mammography but can complicate the process. Choice C is incorrect as implants are designed to be secure and are not likely to be dislodged during a mammogram.

Correct Answer: A

Rationale: The correct answer is A: Administer glucose. Hypoglycemia is low blood sugar, and administering glucose rapidly raises blood sugar levels to restore normal function. Glucagon (choice B) is used for severe hypoglycemia when the individual cannot consume oral glucose. Insulin (choice C) lowers blood sugar levels and is contraindicated in hypoglycemia. Corticosteroids (choice D) can worsen hypoglycemia by affecting glucose metabolism. Administering glucose is the most direct and effective intervention for hypoglycemia.

Correct Answer: A

Rationale: The correct answer is A: Administer diuretics. Diuretics help reduce fluid overload in CHF by increasing urine output and decreasing the workload on the heart. This intervention addresses the underlying issue of fluid retention, a common problem in CHF. Monitoring vital signs (B) is important but does not directly target the primary problem of fluid overload. Monitoring respiratory rate (C) is essential in CHF, but administering diuretics takes precedence in managing fluid balance. Monitoring for arrhythmias (D) is important, but not the most crucial intervention in the management of CHF.

Correct Answer: D

Rationale: The correct answer is D: cirrhosis. Cirrhosis leads to impaired liver function, causing the liver to be unable to effectively metabolize ammonia, leading to high ammonia levels in the blood. Renal failure (choice A) is associated with high creatinine levels, not ammonia. Psoriasis (choice B) is a skin condition unrelated to ammonia levels. Lupus (choice C) is an autoimmune disease affecting various organs, not directly linked to high ammonia levels. In summary, cirrhosis is the only condition among the options that directly impacts liver function and can lead to high ammonia levels in the blood.

Correct Answer: A

Rationale: The correct answer is A (Every 24 hours) because TPN solutions are at high risk for contamination, making it crucial to change the tubing frequently to prevent infection. Changing the tubing every 24 hours helps maintain sterility and reduces the risk of microbial growth. Choices B, C, and D are incorrect because prolonging the tubing change interval increases the likelihood of bacterial colonization and poses a higher risk of infection for the patient receiving TPN. It is essential to adhere to the recommended 24-hour tubing change frequency to ensure patient safety and minimize the potential for complications.
