Pharmacology and the Nursing Process 10th Edition Test Bank Quizlet

Correct Answer: B

Rationale: The correct answer is B: Do not stop medication abruptly. Abruptly stopping propranolol can lead to rebound hypertension and potentially life-threatening complications. The nurse should emphasize the importance of gradual tapering under medical supervision to avoid adverse effects. A: Having potassium levels checked is not directly related to propranolol use for hypertension management. C: Changes in appetite are not specific to propranolol use and may not be a significant concern compared to abrupt cessation of the medication. D: Resuming usual daily activities is important but not as crucial as the correct instruction to avoid abrupt discontinuation of propranolol.

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: 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: C

Rationale: The correct answer is C: Painful and frequent urination. Cloudy penile discharge is a common symptom of urethritis, which is inflammation of the urethra. Painful and frequent urination are classic symptoms of urethritis due to irritation and inflammation of the urinary tract. Throat or rectal infection (choice A) are not typically associated with urethritis. Chancres or vesicles on the genitals (choice B) are more indicative of sexually transmitted infections like syphilis or herpes. Oliguria and flank pain (choice D) are more suggestive of kidney or urinary tract issues rather than urethritis.

Correct Answer: B

Rationale: Step-by-step rationale for choice B being correct: 1. Dehydration leads to electrolyte imbalances, which can exacerbate cardiac dysrhythmias. 2. Small frequent intake of fluids like juices, broth, or milk helps in gradual rehydration without overwhelming the cardiovascular system. 3. This approach allows for better absorption of fluids and nutrients, promoting hydration without causing sudden shifts in electrolyte levels. Summary of why other choices are incorrect: A: Just drinking a glass of water every hour may not address electrolyte imbalances or provide adequate hydration for a client with cardiac dysrhythmias. C: NG replacement may not be necessary if the client can tolerate oral intake, and it is more invasive than needed. D: A rapid IV infusion may lead to sudden changes in electrolyte levels, potentially worsening the dysrhythmias.
