NCLEX-RN Retakes: Eight Times a Year, at Least 45 Test-Free Days Apart

Sublimation is a mature, adaptive ego defense mechanism in which an individual redirects unacceptable, maladaptive impulses—such as aggression or primitive sexual drives—into socially acceptable, constructive, and productive activities like competitive contact sports, art, or hard physical labor. By channeling aggressive energy into rugby, the adolescent constructively expresses hostility without causing interpersonal violence or social dysfunction. Reaction formation by expressing attitudes opposite to underlying drives involves transforming unacceptable urges into their exact opposites, such as displaying excessive friendliness toward an individual one intensely dislikes. Displacement by redirecting anger toward convenient non-threatening objects entails shifting unacceptable emotional feelings from the original threatening source to a safer, less threatening substitute, such as kicking a door after a verbal conflict. Projection by attributing personal hostile feelings to competitive peers occurs when an individual unconsciously disowns unacceptable thoughts or desires and blames others for possessing them, such as accusing teammates of harboring unprovoked hostility. Recognizing adaptive defense mechanisms helps the nurse evaluate psychosocial coping and emotional regulation during behavioral interventions.

Before an abdominal paracentesis, the nurse must ensure that the client empties the urinary bladder, either by voiding or through Foley catheterization. A distended bladder rises superiorly out of the pelvic cavity into the lower abdomen, directly placing it along the path of the entering trocar or needle and dramatically increasing the risk of inadvertent bladder puncture and urinary peritonitis. Placing the client prone with hips elevated is incorrect; the client should be positioned upright in high-Fowler's position or seated at the edge of the bed with feet supported so gravity pools ascites into the lower peritoneal cavity. Administering fresh frozen plasma is not a routine universal requirement unless severe, uncorrected coagulopathy with active bleeding is documented. Requiring a full meal prior to trocar insertion is unnecessary and adds to abdominal fullness and discomfort during the procedure.

Autonomy is the ethical principle that recognizes an individual's right to self-determination, personal freedom, and moral agency in making healthcare choices. A competent adult possesses the legal and ethical right to refuse any medical treatment, including life-sustaining interventions, even if healthcare providers disagree with the outcome. Beneficence represents the moral duty to act in the client's best interest and promote well-being, which in this case conflicts with the client's autonomous choice. Justice pertains to the fair, equitable, and impartial distribution of healthcare resources without bias. Nonmaleficence is the ethical obligation to do no harm, preventing unnecessary injury or suffering. While healthcare providers may feel that refusing life-sustaining care produces harm, forcing unwanted treatment violates bodily integrity and patient autonomy. Honoring the client's informed refusal upholds autonomy above professional paternalism.

The established therapeutic reference range for total serum phenytoin is 10 to 20 mcg/mL. A serum concentration of 14 mcg/mL falls directly within this target window, indicating adequate anticonvulsant suppression with a low risk of dose-related toxicity. A level of 6 mcg/mL is subtherapeutic, meaning the client remains unprotected against seizure activity and requires dose titration or compliance evaluation. A concentration of 26 mcg/mL is supratherapeutic and typically precipitates early neurological toxicity symptoms, such as horizontal nystagmus, ataxia, and slurred speech. A level of 38 mcg/mL represents severe intoxication, which can cause significant central nervous system depression, lethargy, encephalopathy, coma, and cardiovascular instability. Because phenytoin follows non-linear Michaelis-Menten pharmacokinetics, small dosage adjustments at higher concentrations can result in disproportionately large increases in serum levels, necessitating meticulous therapeutic drug monitoring.

Veracity requires providing completely honest and accurate information to clients regarding their health status and care plan. Even when well-meaning family members request that difficult news be concealed to prevent distress, healthcare professionals cannot deceive competent clients or withhold their diagnoses. Providing truthful, accurate, and non-misleading information upholds veracity and enables informed decision-making. Fidelity requires honoring commitments made to the client's family is incorrect because fidelity involves loyalty and honoring professional commitments to the client primarily, not adhering to family requests that compromise truthfulness. Nonmaleficence protects the client from psychological harm is incorrect because while nonmaleficence focuses on doing no harm, family concern about emotional upset does not override the fundamental obligation to share essential medical facts with the client. Beneficence prioritizes actions that promote general well-being is incorrect because beneficence emphasizes acting in the client's best interest, which is fundamentally undermined when essential health information is hidden from the individual. Truthful disclosure forms the foundation of therapeutic nurse-client relationships.
