1. A hypertensive client who has been taking metoprolol (Lopressor) has been prescribed to decrease the dose of the medication. The client asks the nurse why this must be done over a period of 1 to 2 weeks. In formulating a response, the nurse incorporates the understanding that abrupt withdrawal could affect the client in which way?
- A. Result in hypoglycemia
- B. Give the client insomnia
- C. Precipitate rebound hypertension
- D. Cause enhanced side effects of other prescribed medications
Correct answer: C
Rationale: Abruptly stopping metoprolol can lead to rebound hypertension, causing a sudden increase in blood pressure due to the sudden withdrawal of the medication. Gradually tapering the dose helps the body adjust and reduces the risk of this adverse effect. Choices A, B, and D are incorrect. Stopping metoprolol suddenly is not known to result in hypoglycemia, insomnia, or enhanced side effects of other medications.
2. What physical assessment data should the nurse consider a normal finding for a primigravida client who is 12 hours postpartum?
- A. Soft, spongy fundus.
- B. Saturating two perineal pads per hour.
- C. Pulse rate of 56 BPM.
- D. Unilateral lower leg pain.
Correct answer: C
Rationale: The correct answer is C. A pulse rate of 56 BPM can be considered a normal finding for a primigravida client who is 12 hours postpartum. Postpartum bradycardia can occur due to increased stroke volume and decreased vascular resistance after delivery. It is important for the nurse to monitor the client's vital signs and recognize that a lower pulse rate can be expected in the immediate postpartum period. Choices A, B, and D are incorrect because a soft, spongy fundus may indicate uterine atony, saturating two perineal pads per hour is excessive bleeding, and unilateral lower leg pain could suggest deep vein thrombosis, all of which would require further assessment and intervention.
3. An 81-year-old female client has presented to the emergency department accompanied by her daughter with whom she lives. The daughter states that her mother has experienced a recent series of falls, which have resulted in her facial and arm bruises. The client smells of urine and is noticeably emaciated, unkempt, and anxious while the daughter berates her during the nurse's assessment. What is the nurse's responsibility in this situation?
- A. Determine the daughter's legal status with regard to her mother's financial affairs
- B. Report suspected elder abuse
- C. Establish whether the client has a durable power of attorney in place
- D. Obtain medical records regarding prior admissions for similar problems
Correct answer: B
Rationale: In cases of suspected elder abuse, the nurse is responsible for reporting his or her suspicions to the relevant authorities. In this scenario, the signs of elder abuse are evident, such as the client's bruises, unkempt appearance, and the daughter's behavior. Determining the daughter's legal status or the client's power of attorney are not immediate priorities when abuse is suspected. Obtaining medical records for prior admissions is also not the primary concern in this situation.
4. A nurse is contributing to the plan of care for a client who is at risk of developing pressure injuries. Which of the following interventions should the nurse include?
- A. Place the client in a prone position
- B. Place the client in a 30-degree lateral position
- C. Encourage the client to reposition every 4 hours
- D. Place the client in a high Fowler's position
Correct answer: B
Rationale: The correct answer is B: Place the client in a 30-degree lateral position. Positioning the client laterally reduces pressure on bony prominences, improving circulation and helping prevent pressure injuries. Placing the client in a prone position (choice A) increases pressure on the bony prominences, raising the risk of pressure injuries. Similarly, placing the client in a high Fowler's position (choice D) can also increase pressure on certain areas. While encouraging the client to reposition every 4 hours (choice C) is important, the specific lateral positioning is more beneficial in preventing pressure injuries.
5. A healthcare provider is preparing to administer an intramuscular injection to an adult client. Which of the following injection sites should the healthcare provider select?
- A. Deltoid muscle
- B. Dorsogluteal muscle
- C. Vastus lateralis muscle
- D. Rectus femoris muscle
Correct answer: A
Rationale: The deltoid muscle is a common site for intramuscular injections in adults due to its accessibility and muscle mass. It is located in the upper arm and provides a sufficient area for injection. The deltoid muscle is preferred for administering vaccines and other medications that require IM administration. Choice B, the dorsogluteal muscle, is not recommended for intramuscular injections due to the proximity of major nerves and blood vessels in that area, which can lead to nerve damage or injury. Choice C, the vastus lateralis muscle, is more commonly used for infants and young children, while choice D, the rectus femoris muscle, is not typically used for intramuscular injections in adults.
