Test Bank Pharmacology and the Nursing Process

Correct Answer: C

Rationale: The correct answer is C: Autoantibodies. In Hashimoto's thyroiditis, the immune system mistakenly attacks the thyroid gland by producing autoantibodies against thyroid proteins such as thyroglobulin and thyroid peroxidase. These autoantibodies lead to inflammation and destruction of thyroid tissue. Antigen-antibody complexes (choice A) are not the main mechanism in Hashimoto's thyroiditis. Viral (choice B) and bacterial infections (choice D) do not directly cause autoimmune destruction of the thyroid in this condition. Autoantibodies targeting the thyroid gland are the key pathogenic factor in Hashimoto's thyroiditis.

Correct Answer: A

Rationale: Step-by-step rationale: 1. Allowing the client to grasp the nurse's hand firmly assesses grip strength and motor coordination. 2. This step helps evaluate the client's ability to follow instructions and perform a coordinated motor task accurately. 3. Assessing grip strength is essential in determining any muscle weakness or neurological deficits. 4. It also provides insight into the client's motor function and coordination abilities. Summary: - Choice B is incorrect because it focuses on sensory functions rather than motor functions. - Choice C assesses fine motor skills, not grip strength and coordination. - Choice D evaluates cognition and logic, which are not directly related to motor function assessment.

Correct Answer: C

Rationale: The correct answer is C: Use the smallest needle possible for injections. In a client with thrombocytopenia (low platelet count), there is an increased risk of bleeding and bruising. Using the smallest needle possible for injections reduces the risk of causing injury to blood vessels and tissues, minimizing bleeding complications. Limiting visits by family members (choice A) is not directly related to protecting the client's safety. Encouraging wheelchair use (choice B) is not necessary unless indicated for mobility reasons. Maintaining accurate fluid intake and output records (choice D) is important for overall client care but does not directly address the risk of bleeding in thrombocytopenia.

Correct Answer: C

Rationale: The correct answer is C: �This type of surgery rarely affects the ability to have an erection or ejaculation.� This response is appropriate because it provides accurate information that addresses the patient's concern about sexual function without making any false claims. TURP (Transurethral Resection of the Prostate) typically does not impact a patient's ability to have an erection or ejaculate. This reassurance can help alleviate the patient's fears and provide him with accurate information to make an informed decision. Explanation for why the other choices are incorrect: A: �Don�t worry about sterility; sperm production is not affected by this surgery.� - This is incorrect as the concern is more about sexual function than sterility. B: �Would you like some information about implants used for impotence?� - This is incorrect as it jumps to a solution without addressing the patient's specific concern about TURP affecting sexual function. D: �There are many methods of sexual expression that are alternatives to sexual intercourse

Correct Answer: A

Rationale: The correct answer is A because the nurse is using data validation by comparing the time of the last dressing change with the appearance of old and new drainage. This process ensures that the decision to remove the wound dressing is based on accurate and relevant information. By assessing both the time of the last dressing change and the characteristics of the drainage, the nurse is validating the need for the intervention. Option B is incorrect because administering pain medicine based solely on a patient's report of increased pain without further validation does not demonstrate data validation. Option C is incorrect as the nurse immediately requesting an order of potassium without further assessment of the patient's condition is not an example of data validation. Option D is incorrect as elevating a leg cast based solely on a patient's report of decreased mobility without further assessment does not involve data validation.
