A client with a diagnosis of chronic heart failure is receiving digoxin. What is the most important instruction the nurse should provide?

A. Take the medication with a high-fiber meal

B. Monitor pulse rate daily before taking the medication

C. Avoid dairy products while on this medication

D. Discontinue the medication if blurred vision is experienced

Correct Answer: B
Rationale: The most important instruction the nurse should provide is to monitor pulse rate daily before taking the medication. Digoxin can lead to bradycardia, so it is crucial to assess the pulse rate before administering the medication. This practice helps ensure that the heart rate is not too low for the safe use of digoxin. Choice A is incorrect as there is no specific requirement to take digoxin with a high-fiber meal. Choice C is also incorrect because there is no need to avoid dairy products while on digoxin. Choice D is incorrect since blurred vision is not a common side effect of digoxin; hence, it is not the most critical instruction to provide.

Prior to administering morphine sulfate (Morphine), the nurse takes the client's vital signs. Based on which finding should the nurse withhold administration of the medication until the charge nurse is notified?

• A. Temperature of 100.8°F
• B. A pulse rate of 150 beats per minute
• C. A respiratory rate of 10 breaths per minute
• D. A blood pressure of 180/110

Correct Answer: C
Rationale: The correct answer is C because a low respiratory rate is a critical concern when administering opioids like morphine, as they can suppress breathing. A high pulse rate (choice B) and high blood pressure (choice D) are not immediate contraindications for administering morphine. A slightly elevated temperature (choice A) may not necessarily require withholding morphine.

A client is admitted with a diagnosis of myocardial infarction (MI). Which intervention is a priority during the acute phase?

• A. Administer morphine for pain relief
• B. Encourage the client to perform isometric exercises
• C. Position the client flat in bed
• D. Restrict fluid intake

Correct Answer: A
Rationale: During the acute phase of a myocardial infarction (MI), the priority intervention is to administer morphine for pain relief. Morphine not only alleviates pain but also reduces myocardial oxygen demand, which is crucial in the management of MI. Encouraging the client to perform isometric exercises (choice B) can increase myocardial oxygen demand and should be avoided during the acute phase. Positioning the client flat in bed (choice C) may worsen symptoms by increasing venous return and workload on the heart. Restricting fluid intake (choice D) is not a priority intervention during the acute phase of MI; maintaining adequate hydration is important for organ perfusion.

A hospitalized toddler who is recovering from a sickle cell crisis holds a toy and says 'Mine'. According to Erikson's theory of psychosocial development, this child's behavior is a demonstration of which developmental stage?

• A. Autonomy vs. Shame and Doubt
• B. Industry vs. Inferiority
• C. Initiative vs. Guilt
• D. Trust vs. Mistrust

Correct Answer: A
Rationale: The correct answer is A: Autonomy vs. Shame and Doubt. In Erikson's theory, toddlers aged 1-3 years are in the Autonomy vs. Shame and Doubt stage. During this stage, children begin to assert their independence and control over their environment. The behavior of the hospitalized toddler holding a toy and saying 'Mine' demonstrates the child's developing sense of autonomy and ownership. Choices B, C, and D correspond to different stages in Erikson's theory: Industry vs. Inferiority (school-age children), Initiative vs. Guilt (preschoolers), and Trust vs. Mistrust (infants), respectively, which are not applicable to the behavior described.

A client comes to the antepartal clinic and tells the nurse that she is 6 weeks pregnant. Which sign is she most likely to report?

• A. Decreased sexual libido
• B. Amenorrhea
• C. Quickening
• D. Nocturia

Correct Answer: B
Rationale: Amenorrhea is the absence of menstrual periods and is a common early sign of pregnancy, typically reported by a client who is 6 weeks pregnant. Decreased sexual libido (Choice A) may or may not be experienced in early pregnancy, but it is not as specific as amenorrhea. Quickening (Choice C) refers to fetal movements felt by the mother, which usually occurs around 18-20 weeks of pregnancy, not at 6 weeks. Nocturia (Choice D) is waking up at night to urinate and is not typically associated with early pregnancy.
