foundations of nursing practice questions

Correct Answer: A

Rationale: The correct answer is A: Hematologic spread. In this case, the cancer cells have traveled through the bloodstream to reach the bones and liver. This process is known as hematologic spread, where cancer cells enter the blood vessels and spread to distant organs. Lymphatic circulation (B) involves the spread of cancer cells through the lymphatic system, which is less likely in this scenario. Invasion (C) refers to cancer cells infiltrating nearby tissues, not distant organs. Angiogenesis (D) is the process of new blood vessel formation to support tumor growth, but it does not explain the spread of cancer cells to other organs.

Correct Answer: C

Rationale: Rationale for Correct Answer (C): 1. The newer antihistamines, such as second-generation antihistamines like loratadine or cetirizine, are designed to cause less sedation compared to older antihistamines like diphenhydramine. 2. These newer antihistamines have a lower affinity for crossing the blood-brain barrier, reducing the sedative effects. 3. Therefore, suggesting that the newer antihistamines are different and cause less sedation is the best response to address the patient's concerns. Summary of Incorrect Choices: A. While some newer antihistamines may be combined with decongestants to offset drowsiness, this is not a consistent feature of all newer antihistamines. B. Developing tolerance to sedation after a few months is not a common or reliable response to antihistamines. D. Taking antihistamines at bedtime may help with sedation, but it does not address

Correct Answer: D

Rationale: The correct answer is D: Risk for Self-Care Deficit Related to Skin Lesions. Patients with atopic dermatitis may experience difficulty performing self-care tasks due to pain, itching, and limitations in hand mobility caused by skin lesions. This diagnosis addresses the potential challenges the patient may face in maintaining personal hygiene and managing their skin condition. Explanation for why other choices are incorrect: A: Risk for Disturbed Body Image Related to Skin Lesions - While atopic dermatitis may impact body image, the priority in this case is the patient's ability to perform self-care. B: Risk for Disuse Syndrome Related to Dermatitis - Disuse syndrome is not typically associated with atopic dermatitis. C: Risk for Ineffective Role Performance Related to Dermatitis - This diagnosis focuses on the patient's ability to fulfill their roles, which may not be directly impacted by atopic dermatitis.

Correct Answer: B

Rationale: The correct answer is B: Protect the patient's airway. In anaphylaxis, airway compromise can lead to respiratory distress and even respiratory arrest. The priority is to ensure the patient has a patent airway to maintain oxygenation. This can be achieved through interventions such as positioning, oxygen therapy, and potentially intubation if needed. Monitoring the patient's level of consciousness (A) is important but secondary to ensuring airway patency. Providing psychosocial support (C) is not the immediate priority in anaphylaxis. Administering medications (D) is also important but only after ensuring the airway is protected.

Correct Answer: D

Rationale: The correct answer is D: Surgical intervention. Cataracts are a clouding of the lens in the eye, which can lead to vision impairment. Surgery is the most common and effective treatment for cataracts, involving the removal of the cloudy lens and replacement with an artificial one. Antioxidant supplements (Choice A) may help prevent cataracts but are not a treatment for existing ones. Eyeglasses or magnifying lenses (Choice B) can help with vision correction but do not address the cataracts themselves. Corticosteroid eye drops (Choice C) are used for treating inflammation in the eye, not cataracts. Therefore, surgical intervention is the most appropriate treatment option for age-related cataracts.
