Correct Answer: C

Rationale: The correct answer is fidelity. Fidelity is the ethical principle that refers to keeping professional promises or obligations. Veracity, however, relates to truth-telling. Autonomy is about client self-determination and decision-making. Beneficence, on the other hand, involves doing good and is crucial in the provision of nursing care.

Correct Answer: D

Rationale: Taking corticosteroids in the morning mimics the body's natural release of cortisol, which follows a diurnal pattern with higher levels in the morning. This timing helps regulate the body's inflammatory response and minimizes potential side effects. Answer A is not the primary reason for morning dosing, as adherence concerns can be addressed through other means. Answer B is incorrect since fluid retention is not influenced by the timing of prednisone administration. Answer C is also incorrect as prednisone absorption is not significantly affected by whether it is taken with breakfast or not.

Correct Answer: B

Rationale: The correct answer is 'individuals with psychiatric disorders' increased susceptibility to substance abuse.' It is crucial to inquire about substance abuse during admission to an acute-care psychiatric unit because individuals with psychiatric disorders are more prone to experiencing substance abuse issues. Addressing substance abuse is vital for effective treatment and to prevent relapse in psychiatric disorders. Option A is incorrect as it focuses on the prevalence of psychiatric illness in addicted populations rather than the relationship between psychiatric disorders and substance abuse. Option C is incorrect as it exaggerates the ease of detecting and diagnosing substance disorders in acute-care psychiatric settings. Option D is incorrect as undetected substance problems can indeed significantly impact the treatment of psychiatric disorders, but the main reason for inquiring about substance abuse is the increased susceptibility of individuals with psychiatric disorders to such issues.

Correct Answer: B

Rationale: The correct answer is 'pharmacodynamic.' Pharmacodynamics pertain to the effect of a drug on receptors, explaining how drugs affect tissues. Pharmaceutical reactions refer to chemical reactions between drugs before administration or absorption, not their effect on tissues. Pharmacokinetic reactions involve how the body affects the drug, not the tissue. Drug incompatibilities are essentially pharmaceutical reactions, not the specific effects on tissues seen in pharmacodynamic reactions.

Correct Answer: C

Rationale: The correct answer is the kidney(s) because most drugs are excreted in the urine, either as the parent compound or as drug metabolites. The skin is not the primary organ for drug elimination; only a few drugs are excreted in sweat. The lung(s) primarily excrete volatile gases with expiration, not drugs. While the liver metabolizes drugs, it is the kidney(s) that primarily eliminate drugs through urine, especially those with a molecular weight above 300.
