In the treatment of symptomatic bradycardia, which medication is most commonly recognized?
- A. Questran
- B. Digitalis
- C. Nitroglycerin
- D. Atropine
Correct Answer: D
Rationale: Atropine is the medication most commonly recognized for the treatment of symptomatic bradycardia because it increases the rate of conduction in the AV node, helping to alleviate bradycardia. Questran is a medication used to lower cholesterol levels and is not indicated for bradycardia. Digitalis, such as Digoxin, is used for heart failure and atrial fibrillation but not typically for bradycardia. Nitroglycerin is primarily used for angina and not bradycardia.

What could be a possible cause for the symptoms experienced by the client in Question 28?
- A. iron deficiency
- B. folate deficiency
- C. peptic ulcer
- D. iron overload
Correct Answer: A
Rationale: Given the client's symptoms of fatigue, shortness of breath, and lightheadedness, along with her gender and fad dieting, the most likely cause is iron deficiency. Iron deficiency commonly presents with these symptoms due to decreased oxygen-carrying capacity in the blood. Folate deficiency would typically present with different symptoms such as mouth sores and changes in skin, not fitting the client's presentation. Peptic ulcer would manifest with abdominal pain, not primarily with the symptoms described. Iron overload would present with symptoms such as joint pain and fatigue, which are not consistent with the client's presentation.
The client asked about the role of leptin in the body. Which response should the nurse provide?
- A. It increases food intake in clients, thereby promoting obesity.
- B. It assists in the regulation of steroids.
- C. It increases the total fat mass of people who are obese.
- D. It might decrease the total fat mass in the bodies of people who are obese.
Correct Answer: D
Rationale: Leptin is a protein hormone expressed in fat cells that regulates fat cell percentage in the body. It is associated with increased energy expenditure and decreased food intake through hypothalamic control. In obese individuals, there may be insensitivity or resistance to leptin's effects. Leptin influences other hormones like insulin and genetic factors related to fat regulation. Therefore, the correct response is that leptin might decrease total fat mass in obese individuals as it is involved in energy balance and fat regulation. Choices A, B, and C are incorrect because leptin does not increase food intake or promote obesity; it does not assist in the regulation of steroids, and it does not increase total fat mass in people who are obese.
A client needs to rapidly achieve a therapeutic plasma drug concentration of a medication. Rather than wait for steady state to be achieved, the physician might order:
- A. a maintenance dose.
- B. a loading dose.
- C. a medication with no first-pass effect.
- D. the medication to be given intravenously.
Correct Answer: B
Rationale: To rapidly achieve a therapeutic plasma drug concentration, a loading or priming dose is ordered. This dose quickly establishes the desired drug level. It is calculated by multiplying the volume of distribution by the desired plasma drug concentration. A maintenance dose, like choice A, is used to maintain the therapeutic level after the loading dose. Waiting for steady state without a loading dose would take five drug half-lives. Choice C, a medication with no first-pass effect, does not directly address the need for rapid attainment of therapeutic levels. While intravenous administration (choice D) offers excellent bioavailability, a single dose by this route may not achieve the desired therapeutic plasma concentration as rapidly as a loading dose.
A nurse is caring for a client with an elevated cortisol level. The nurse can expect the client to exhibit symptoms of:
- A. urinary excess
- B. hyperpituitarism
- C. urinary deficit
- D. hyperthyroidism
Correct Answer: C
Rationale: Elevated cortisol levels can lead to sodium and fluid retention and potassium deficit, resulting in urinary deficit. This imbalance in electrolytes and fluid can cause a decrease in urinary output. Choices B, hyperpituitarism, and D, hyperthyroidism, are incorrect as they do not directly relate to the symptoms expected with elevated cortisol levels. Option A, urinary excess, is also incorrect as high cortisol levels typically lead to fluid retention and urinary deficit, not excess.
What is the most effective strategy to assist a client in recognizing and using personal strength?
- A. Encouraging the client's self-identification of strengths.
- B. Promoting the client's active external thinking.
- C. Listening to the client and providing advice as needed.
- D. Assisting the client in maintaining an external locus of control.
Correct Answer: A
Rationale: Encouraging the client to identify their own strengths is empowering and helps build self-awareness and self-confidence. This strategy promotes autonomy and self-efficacy, enabling the client to recognize and utilize their personal strengths effectively. Option B, promoting the client's active external thinking, is vague and not directly related to recognizing personal strengths. Option C, listening to the client and providing advice as needed, focuses more on the nurse's role rather than empowering the client to recognize their strengths independently. Option D, assisting the client in maintaining an external locus of control, goes against the goal of helping the client recognize and utilize their internal strengths.
