A nurse is caring for a client who is prescribed a selegiline transdermal patch. Which of the following manifestations should the nurse anticipate the prescription will improve?

A. Abdomen: The abdomen is typically used for subcutaneous injections, such as insulin or heparin, due to its fatty tissue. It is not ideal for intradermal injections, which require a thin layer of skin to allow for proper absorption and observation of a wheal.

B. Deltoid: The deltoid muscle is commonly used for intramuscular injections, not intradermal ones. Using this site for intradermal injections could result in the medication being deposited too deeply, affecting absorption and test accuracy.

C. Back of the upper arm: The inner surface of the forearm or the back of the upper arm is the preferred site for intradermal injections, such as tuberculosis or allergy testing. This area has thin skin, minimal subcutaneous fat, and allows for easy visualization of the wheal and monitoring for reactions.

D. Upper back: While the upper back has subcutaneous tissue, it is not commonly used for intradermal injections because it is less accessible for observation and assessment of local reactions. Proper site selection is important for safety and effectiveness.

Rationale for correct choices

• Mania: The client exhibits classic signs of mania, including elevated mood, excessive energy, decreased need for sleep, impulsive behavior such as excessive spending, and pressured, disorganized speech. These behaviors are consistent with a manic episode rather than delirium, catatonia, major depressive disorder, or panic disorder.

• Euphoric mood: The client demonstrates an overly joyous and elevated sense of self-confidence, which is characteristic of euphoric mood during a manic episode. Euphoric mood contributes to impulsive behaviors, distractibility, and poor judgment. This finding aligns with the manic episode and helps distinguish mania from other psychiatric conditions that primarily involve negative mood states or anxiety.

Rationale for incorrect choices

• Delirium: Although the client is disoriented to place and exhibits poor concentration, delirium typically develops acutely and fluctuates, often secondary to a medical condition or substance use. The client’s sustained elevated mood, impulsive behavior, and pressured speech are not consistent with delirium.

• Panic disorder: Panic disorder involves sudden episodes of intense fear, palpitations, and autonomic hyperactivity, which are not reported in this client. The client’s persistent elevated mood, lack of fear-driven episodes, and impulsive behaviors do not align with panic disorder symptoms.

• Catatonia: Catatonia is characterized by motor immobility, stupor, mutism, or rigidity, which contrasts sharply with the client’s constant movement, hyperactivity, and pressured speech. The client demonstrates goal-directed and excessive activity rather than the motor inhibition seen in catatonia.

• Major depressive disorder: Major depressive disorder involves persistent low mood, anhedonia, and lack of energy, which is the opposite of the client’s elevated, euphoric mood and hyperactivity. The client’s impulsivity and pressured speech indicate a manic state rather than depression. Depressive symptoms are not evident in the current presentation.

• Magical thinking: Although magical thinking can occur in some psychiatric conditions, the client’s primary feature is euphoric mood and goal-directed hyperactivity. There is no evidence of superstitious beliefs or illogical thought processes driving behavior.

• Alogia: Alogia refers to poverty of speech or reduced verbal output, which is inconsistent with the client’s pressured and loud speech. The client demonstrates excessive verbal output, indicating elevated energy rather than speech poverty.

• Anhedonia: Anhedonia, or lack of pleasure, is a symptom of depression, which is absent here. The client’s enjoyment of activities, desire to host parties, and euphoric mood contradict the presence of anhedonia.

• Hypervigilance: Hypervigilance involves excessive alertness and scanning for threats, often seen in anxiety or PTSD. While the client reports seeing hallucinations, these perceptual disturbances are more consistent with psychosis, not hypervigilance. The primary finding supporting mania is euphoric mood rather than anxiety-driven alertness.
