The nurse is assessing an adolescent female diagnosed with anorexia nervosa who is admitted to the unit with severe malnutrition and electrolyte imbalance.
Which pathological process results from the adolescent's consistent maladaptive behavior?

Choice A rationale:

Urticaria is a skin condition characterized by the sudden appearance of raised, itchy, and red welts on the skin. It is an objective finding because it can be observed and assessed visually. The presence of urticaria may indicate an allergic reaction or another underlying condition.

Choice B rationale:

Hypertension is a subjective finding because it cannot be directly observed. It requires blood pressure measurement to confirm, making it a subjective parameter.

Choice C rationale:

Diaphoresis refers to excessive sweating, which can be observed and assessed visually. It is an objective finding and may be indicative of various conditions, including anxiety or fever.

Choice D rationale:

Nausea is a subjective symptom because it is a sensation that the client experiences and reports. It cannot be directly observed by the nurse, making it a subjective parameter.

Choice E rationale:

Anxiety is a subjective symptom, as it is a mental and emotional state experienced by the client. It cannot be directly observed, making it a subjective parameter.

Choice F rationale:

Edema is an objective finding because it can be visually assessed by the nurse. Edema is the accumulation of excess fluid in body tissues, and its presence or absence can be objectively determined.

Choice A rationale:

Tetracycline antibiotics can form insoluble complexes with calcium, reducing their absorption when taken together. Therefore, advising the client to continue taking calcium supplements with food while on tetracycline therapy is not recommended as it may decrease the effectiveness of the antibiotic.

Choice B rationale:

The nurse should advise the client to avoid taking calcium supplements while on tetracycline therapy. Calcium-containing products (such as supplements, dairy products, and antacids) should be taken at least 2 hours before or after tetracycline administration to minimize the interference with drug absorption.

Choice C rationale:

Taking calcium supplements with tetracycline, even with plenty of water, can still lead to reduced drug absorption due to the formation of insoluble complexes. Therefore, this advice is not appropriate.

Choice D rationale:

The nurse should recommend that the client take calcium supplements at least 2 hours before or after tetracycline. This approach ensures that the client receives the full therapeutic benefit of the antibiotic while still meeting their calcium needs separately.
