Correct Answer: B

Rationale: The correct answer is B: I.V. administration and urinary excretion. Lomustine is typically administered intravenously, allowing for rapid systemic distribution. The drug is metabolized in the liver and excreted primarily through the kidneys, thus the urinary route. This choice is correct as lomustine's pharmacokinetics align with this pattern. A: Oral administration and urinary - While some drugs are administered orally, lomustine is not typically given orally due to poor bioavailability. C: I.V. administration and fecal excretion - Lomustine is not primarily excreted via the feces, making this choice incorrect. D: Oral administration and fecal excretion - Lomustine is not primarily excreted via the feces, making this choice incorrect.

Correct Answer: B

Rationale: The correct answer is B: inadequate supply of oxygen to the myocardium. Angina pectoris is chest pain or discomfort caused by reduced blood flow to the heart muscle. This lack of oxygenated blood supply to the myocardium leads to ischemia, resulting in the characteristic chest pain. Choice A is incorrect as it refers to a decrease in alveolar surface area for gas exchange, which is related to conditions like emphysema, not angina. Choice C is incorrect as it pertains to pulmonary circulation, not coronary circulation. Choice D is incorrect as an increase in alveolar surface area would not be a cause of angina pectoris.

Correct Answer: D

Rationale: Pulmonary edema causes an increase in pressure in the pulmonary circulation, leading to an alteration in afterload due to increased resistance. It also causes fluid accumulation in the pulmonary vessels, affecting preload. Additionally, the heart may compensate by increasing contractility. Therefore, all of the above choices are altered in pulmonary edema. The incorrect choices are A, B, and C individually as they only represent one aspect of the alterations seen in pulmonary edema, while the correct answer D encompasses all three factors affected in this condition.

Correct Answer: A

Rationale: The correct answer is A because it follows the correct format of a nursing diagnosis: "Problem related to Etiology." In this case, "Decreased cardiac output" is the problem, and "altered myocardial contractility" is the cause. This format helps identify the specific issue and its underlying cause, allowing for targeted interventions. Choice B is incorrect as it doesn't follow the problem-etiology format and lacks specificity. Choice C is also incorrect as it lacks a clear nursing diagnosis and specific etiology. Choice D is incorrect as it presents a symptom rather than a nursing diagnosis with an associated cause. Overall, choice A is the best option as it provides a clear, specific nursing diagnosis that guides appropriate nursing interventions.

Correct Answer: C

Rationale: The correct answer is C: Asymmetry. The ABCD method is a mnemonic used for assessing skin lesions for possible skin cancer. The A in ABCD stands for Asymmetry, indicating that the lesion is not symmetrical in shape or color. Skin cancers often exhibit asymmetrical features. Actinic (Choice A) refers to sun damage, Arcus (Choice B) is a term related to the eye, and Assessment (Choice D) is a general term that does not specifically relate to skin lesion evaluation. By focusing on asymmetry, healthcare providers can identify potential skin cancer lesions early for further evaluation and treatment.
