Pharmacology and the Nursing Process 10th Edition Test Bank Quizlet

Correct Answer: A

Rationale: The correct answer is A: Trousseau's sign. A serum calcium level of 7.2mg/dl indicates hypocalcemia. Trousseau's sign is a clinical manifestation of hypocalcemia, characterized by carpal spasm induced by inflating a blood pressure cuff above systolic pressure. This occurs due to increased neuromuscular excitability from low calcium levels. Hegar's sign (B) is associated with pregnancy, Homan's sign (C) is a clinical test for deep vein thrombosis, and Goodell's sign (D) is a softening of the cervix during pregnancy. These signs are not relevant to a client with hypocalcemia.

Correct Answer: C

Rationale: The correct answer is C: Hypercalcemia. In bone cancer, there can be excessive release of calcium from the bones, leading to elevated blood calcium levels. This can result in various complications such as kidney stones, cardiac arrhythmias, and weakness. Hyperkalemia (choice A) is not commonly associated with bone cancer. Hyponatremia (choice B) is more commonly seen in conditions like heart failure or kidney disease. Hypomagnesemia (choice D) is not a common electrolyte disturbance in bone cancer.

Correct Answer: B

Rationale: The correct answer is B because maintaining the head of the bed at a 30-degree angle can cause the radioactive material to shift within the client's body, increasing the risk of radiation exposure. This position should be avoided to prevent displacement of the applicator. A: Strict bed rest is appropriate to minimize movement and dislodgement of the applicator, ensuring proper treatment delivery. C: Providing a bed bath does not pose a radiation hazard as long as proper precautions are taken. D: Checking the applicator's position every 4 hours is essential for monitoring and ensuring it remains in place to deliver the intended treatment.

Correct Answer: A

Rationale: The correct answer is A: Decreased resistance to infection. Lymphocytes are a crucial part of the immune system, responsible for fighting off infections. A decrease in the number of lymphocytes with age leads to a weakened immune response, making individuals more susceptible to infections. - Choice B: Cognitive problems, is not directly related to lymphocyte levels. - Choice C: Urinary incontinence, is not a typical effect of decreased lymphocytes. - Choice D: Decrease in various blood components, is too broad and not specific to the role of lymphocytes in immunity.
