What is smokeless tobacco?
- A. Not addicting
- B. Proven to be carcinogenic
- C. Easy to stop using
- D. A safe alternative to cigarette smoking
Correct Answer: B
Rationale: Smokeless tobacco refers to tobacco products that can be used without being smoked. These products usually come in the form of snuff, chewing tobacco, or dissolvable tobacco products. While smokeless tobacco does not involve the inhalation of smoke, it is still proven to be carcinogenic. The most significant health risk associated with smokeless tobacco is the potential to develop various types of cancer, including oral, esophageal, and pancreatic cancer. Therefore, it is crucial to understand that using smokeless tobacco is not a safe alternative to cigarette smoking, as it still poses serious health risks.

The initial neurological symptom of Guilain-Barre Syndrome is:
- A. Absent tendon reflex
- B. Paresthesia of the legs
- C. Dysrhythmias
- D. Transient hypertension
Correct Answer: B
Rationale: The initial neurological symptom of Guillain-Barre Syndrome (GBS) is typically paresthesia, which is a tingling or numbness sensation in the legs. GBS is an autoimmune disorder that affects the peripheral nervous system, leading to muscle weakness and paralysis. As the condition progresses, symptoms may worsen and may include absent tendon reflexes, weakness in the arms and legs, and difficulty breathing. However, paresthesia is often one of the earliest and most common symptoms of GBS.
. A client is admitted to the health care facility for evaluation for Addison's disease. Which laboratory test result best supports a diagnosis of Addison's disease?
- A. Blood urea nitrogen (BUN) level of
- B. Serum sodium level of 134 mEq/L
- C. Serum potassium level of 5.8 mEq/L
- D. Blood glucose level of 90 mg/dl
Correct Answer: C
Rationale: Addison's disease, also known as adrenocortical insufficiency, is characterized by a deficiency in adrenal cortex hormones, particularly glucocorticoids and mineralocorticoids. One of the characteristic findings in Addison's disease is hyperkalemia, which is an elevated serum potassium level. This is due to the lack of aldosterone production by the adrenal glands, leading to decreased potassium excretion by the kidneys. Therefore, a serum potassium level of 5.8 mEq/L would best support a diagnosis of Addison's disease among the given laboratory test results.
A patient is being taught the action of digoxin, which is an inotropic agent. The nurse defines an inotropic agent as a medication that has which of the following actions?
- A. Decreases heart rate
- B. Increases conduction time
- C. Increases heart rate
- D. Strengthens heart contraction
Correct Answer: D
Rationale: An inotropic agent, such as digoxin, is a medication that strengthens the contraction of the heart muscle. It works by increasing the force of each heartbeat, helping the heart pump more efficiently. This can be beneficial in conditions such as heart failure or certain types of arrhythmias where the heart's pumping ability is compromised. Inotropic agents do not decrease heart rate, increase conduction time, or increase heart rate; their primary action is to enhance the heart's contractility.
