Pharmacology and the Nursing Process 10th Edition Test Bank Quizlet

Correct Answer: A

Rationale: The correct answer is A: 11mEq/L. In renal failure, the kidneys are unable to excrete excess magnesium, leading to hypermagnesemia. The patient's symptoms of stomach distress and ingesting antacids suggest magnesium intake. A Mg level of 11mEq/L aligns with symptoms like flushed face and weakness. Choices B, C, and D are too low for hypermagnesemia symptoms and would not explain the patient's presentation.

Correct Answer: D

Rationale: The correct answer is D. Asking about seeing halos around lights is relevant to assessing the patient's eye health as it could indicate conditions like glaucoma or cataracts. Upper respiratory infections (A), riding in a car (B), and scuba diving (C) are not directly related to eye health assessment. By focusing on symptoms directly related to the eyes, the nurse can gather relevant information for a more accurate assessment.

Correct Answer: B

Rationale: The correct answer is B: Administering platelets, as ordered to maintain an adequate platelet count. In ITP, the client has low platelet count leading to risk of bleeding. Administering platelets helps raise platelet levels and prevent bleeding complications. Teaching coughing and deep-breathing techniques (A) is important for preventing respiratory infections but not directly related to ITP. Giving aspirin (C) is contraindicated as it can further decrease platelet count. Administering stool softeners (D) is important for preventing straining but not specific to managing ITP.

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.

Correct Answer: A

Rationale: The correct answer is A because decorticate posturing is characterized by flexion of both upper and lower extremities. This occurs due to damage to the cerebral hemispheres, resulting in abnormal muscle contractions. Choice B describes decerebrate posturing, which is associated with extension of elbows and knees. Choice C is incorrect as it describes abnormal posturing seen in other conditions. Choice D is also incorrect as it describes a different type of abnormal posturing.
