Pharmacology and the Nursing Process 10th Edition Test Bank Quizlet

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: C

Rationale: Step 1: Reading labels carefully on vials containing flush solutions for locks is crucial to ensure the correct solution is being used. Step 2: Potassium chloride should not be used to flush locks as it can be fatal if administered incorrectly. Step 3: By carefully reading labels, the nurse can verify that the correct solution is being used, thus minimizing the risk of using potassium chloride. Summary: - Choice A is incorrect as using a dilute form of potassium chloride does not address the issue of incorrect administration. - Choice B is incorrect as warming the solution does not prevent the risk associated with using potassium chloride. - Choice D is incorrect as replacing locks does not address the root cause of the issue, which is improper administration.

Correct Answer: D

Rationale: The correct answer is D, "Ineffective thermoregulation related to dehydration." The client's high serum glucose level of 618mg/dl indicates severe hyperglycemia, leading to dehydration. The client's hot, dry skin and elevated temperature can be signs of dehydration, impacting the body's ability to regulate temperature. Dehydration can also affect other vital signs, contributing to the elevated heart rate and low blood pressure. Addressing ineffective thermoregulation is crucial as it can lead to further complications. Choices A, B, and C are not the highest priority because addressing dehydration and ineffective thermoregulation takes precedence due to the immediate risk of complications such as heatstroke or hypothermia. Deficient volume, decreased cardiac output, and imbalanced nutrition are important but not as urgent in this scenario.

Correct Answer: D

Rationale: The correct answer is D: Autoimmune reaction. Guillain-Barre Syndrome is an autoimmune disorder where the immune system mistakenly attacks the peripheral nerves, leading to muscle weakness and paralysis. This is supported by the patient's presentation of weakness in the legs. Bacterial infection (A) can trigger Guillain-Barre Syndrome, but it is not the root cause. High-fat diet (B) and heredity (C) are not associated with the development of this syndrome. In summary, autoimmune reaction is the primary mechanism underlying Guillain-Barre Syndrome, resulting in the patient's muscle weakness and inability to walk.

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.
