Correct Answer: A

Rationale: The correct answer is A: Monthly testicular self-examination. This is the best way to detect testicular cancer early because it allows individuals to become familiar with the normal size, shape, and texture of their testicles, making it easier to notice any changes or abnormalities. Self-examination is cost-effective, convenient, and can be done regularly to monitor for any signs of cancer. Annual physician examination (B) may not be frequent enough for early detection. Yearly digital rectal examination (C) is not relevant for detecting testicular cancer. Annual ultrasonography (D) is not recommended as a routine screening tool for testicular cancer.

Correct Answer: C

Rationale: The correct answer is C: trace minerals. TPN solutions typically include dextrose for energy, electrolytes for maintaining fluid balance, and amino acids for protein synthesis. Trace minerals are not typically included in TPN solutions as they are only required in small amounts and can be toxic in excess. Therefore, it is not likely to be in the solution. The other choices (A, B, D) are essential components of TPN solutions necessary for meeting the nutritional needs of the patient.

Correct Answer: D

Rationale: The correct answer is D: 24 hours. Compartment syndrome occurs when pressure within a closed muscle compartment increases, leading to decreased circulation and potential tissue damage. Monitoring is crucial as irreversible damage can occur if left untreated. The 6 Ps (pain, pallor, pulselessness, paresthesia, paralysis, pressure) are key indicators. Waiting for 48 hours (choice A) or 12 hours (choice C) is too long and can result in severe consequences. 2 hours (choice B) is too short a timeframe to assess for irreversible damage development, making 24 hours (choice D) the most appropriate timeframe for monitoring and intervention.

Correct Answer: C

Rationale: The correct answer is C: Puffiness at the site. This indicates infiltration of the infusion, where the medication or fluid leaks into the surrounding tissue instead of entering the bloodstream. Puffiness is a sign of fluid accumulation due to the infiltration. Redness at the site (A) may indicate infection, pain (B) can be due to various reasons, and exudate (D) may suggest infection or irritation, but they are not specific to infiltration. Infiltration assessment involves checking for swelling, coolness, and blanching around the infusion site.

Correct Answer: C

Rationale: The correct answer is C because it is essential for the nurse to ensure accurate and up-to-date vital signs before administering medications. By asking the NAP to record the patient's vital signs, the nurse can make informed decisions about the patient's condition and prevent any potential complications. Choice A is incorrect because administering medications without knowing the patient's vital signs, particularly if they are abnormal, can be dangerous. Choice B is not the best course of action as it delays the crucial step of obtaining the vital signs. Choice D is incorrect as omitting vital signs without assessment could compromise patient safety. Therefore, choice C is the most appropriate response to ensure patient well-being and medication safety.
