Foundations and Adult Health Nursing Study Guide Answers

Correct Answer: A

Rationale: The clinical presentation of fatigue, pallor, exertional dyspnea along with the laboratory findings of severe anemia, low serum iron, low transferrin saturation, and elevated TIBC are consistent with iron deficiency anemia. In iron deficiency anemia, there is inadequate iron available for erythropoiesis leading to microcytic hypochromic anemia. The low serum iron and transferrin saturation, along with the elevated TIBC, indicate decreased iron stores and increased iron-binding capacity as the body tries to compensate for the deficiency by increasing absorption and recycling of iron. Anemia of chronic disease typically presents with mild to moderate anemia, normal to low TIBC, and low transferrin saturation due to iron sequestration in macrophages. Sideroblastic anemia usually has elevated serum iron, high saturation, and normal to low TIBC. Thalassemia presents with microcytic hyp

Correct Answer: A

Rationale: The patient's presentation of a pruritic, annular rash with fine scaling and central clearing, affecting the trunk and proximal extremities, following exposure to a new soap and laundry detergent is most consistent with tinea corporis, commonly known as ringworm. Ringworm is a superficial fungal infection caused by dermatophytes that can present with circular or annular lesions with central clearing and scaling. The exposure to new soap and laundry detergent may have disrupted the skin's microbiome, making it more vulnerable to fungal infections like tinea corporis. Nummular eczema typically presents as coin-shaped plaques rather than annular lesions, while pityriasis rosea presents with a herald patch followed by smaller similar lesions in a "Christmas tree" distribution. Lichen planus would not typically be associated with exposure to new soap and laundry detergent but can have distinct purple, polygonal papules.

Correct Answer: B

Rationale: Encouraging the patient to practice controlled coughing techniques would be the most appropriate intervention to address the symptoms of chronic cough and excessive sputum production in a patient with end-stage COPD receiving palliative care. Controlled coughing techniques can help the patient effectively clear respiratory secretions and improve airway clearance without the need for additional medications or interventions. This approach focuses on optimizing the patient's ability to manage their symptoms and maintain comfort, which aligns with the goals of palliative care. Administering bronchodilator medications, prescribing mucolytic medications, or referring the patient to a respiratory therapist for breathing exercises may have limited effectiveness in this advanced stage of the disease, and controlled coughing techniques would be a more practical and patient-centered approach to symptom management.

Correct Answer: B

Rationale: Running water in the sink or shower is a priority nursing measure to stimulate the sensation of voiding in postpartum mothers experiencing difficulty due to edema and trauma of the perineum. The sound and sight of running water can help relax the pelvic floor muscles and trigger the urge to void. This technique is commonly used in clinical practice to facilitate voiding and prevent urinary retention in postpartum women.

Correct Answer: B

Rationale: Dental caries, commonly known as tooth decay, is characterized by the irreversible demineralization of the enamel and dentin due to acids produced by bacterial activity. This process leads to cavitation and destruction of the tooth structure, ultimately resulting in the formation of a cavity. Gingivitis is inflammation of the gums, periodontitis is inflammation and infection of the supporting structures of the teeth (gums, bone, and ligaments), and a dental abscess is a collection of pus in the tissues surrounding the tooth, none of which are specifically related to the irreversible demineralization of enamel and dentin seen in dental caries.
