Nokea
As the nurse cares for a patient with angioedema, differs from urticaria in that angioedema is characterized by which of the following?
- A. Angioedema is more pruritic.
- B. Angioedema has small, fluid-filled vesicles
- C. Angioedema has a deeper and more that crust.
- D. Angioedema lasts a shorter time.
Correct Answer: C
Rationale: Step-by-step rationale for choice C: Angioedema differs from urticaria as it involves deeper swelling in the dermis and subcutaneous tissue, leading to a more profound and firm texture. This contrasts with urticaria, which presents as superficial, raised wheals on the skin. Therefore, option C is correct.
Summary of other choices:
A: Angioedema is not typically associated with intense itching, so it is not more pruritic than urticaria.
B: Angioedema does not have small, fluid-filled vesicles like in allergic contact dermatitis.
D: Angioedema tends to last longer than urticaria, making this statement incorrect.

The nurse is preparing an intravenous infusion of phenytoin (Dilantin) as prescribed by the physician for the client with seizures. Which of the following solutions will the nurse plan to use to dilute this medication?
- A. Dextrose 5%
- B. Lactated Ringer’s solution
- C. Normal saline solution
- D. Dextrose 5% and half-normal saline (0.45%)
Correct Answer: C
Rationale: The correct answer is C: Normal saline solution. Phenytoin is incompatible with dextrose solutions, so options A and D are incorrect. Lactated Ringer's solution contains calcium, which can interact with phenytoin, leading to precipitation. Therefore, option B is also incorrect. Normal saline is the most compatible diluent for phenytoin, maintaining the drug's stability and effectiveness. It is essential to use the appropriate diluent to prevent adverse reactions or drug interactions.
Which type of neuron transmits impulses from the central nervous system to the muscles and glands?
- A. Afferent
- B. Affective
- C. Efferent
- D. Effective A1 PASSERS TRAINING, RESEARCH, REVIEW & DEVELOPMENT COMPANY MEDICAL SURGICAL NURSING SET M
Correct Answer: C
Rationale: The correct answer is C: Efferent neurons transmit impulses from the central nervous system to muscles and glands. This is because efferent neurons are responsible for carrying motor signals away from the central nervous system to control muscle movement and gland secretion.
Afferent neurons (choice A) transmit sensory information from the body to the central nervous system. Affective (choice B) is not a term used in neuroscience for describing neuron functions. Effective (choice D) is not a term used in neuroscience and does not describe the specific function of transmitting impulses from the central nervous system to muscles and glands.
A nurse is completing an assessment using the PQRST to obtain data about the patient’s chest pain. Match the questions to the components of the PQRST that the nurse will be using.
- A. Where is the pain located?
- B. What causes the pain?
- C. Does it come and go?
- D. What does the pain feel like?
Correct Answer: A
Rationale: The correct answer is A: Where is the pain located? This question corresponds to the "P" in PQRST, which stands for Provocation/Palliation. By asking where the pain is located, the nurse is gathering information about what triggers or relieves the pain, aiding in the assessment of the chest pain. The other choices are incorrect because:
B: What causes the pain? - This question corresponds to the "Q" in PQRST, which stands for Quality. It focuses on understanding the characteristics of the pain, not the cause.
C: Does it come and go? - This question corresponds to the "R" in PQRST, which stands for Radiation. It pertains to whether the pain spreads to other areas, not if it comes and goes.
D: What does the pain feel like? - This question corresponds to the "S" in PQRST, which stands for Severity. It relates to the intensity of the pain, not its location.
Which of the ff nursing interventions is essential for a client during the Schilling test?
- A. Collecting urine 24-48 hrs after the client has received nonradioactive B12
- B. Collecting blood samples of 50 ml for 24-48 hrs after the client has received the nonradioactive B12
- C. Not allowing any oral fluid consumption for 24-48 hrs after the client has received nonradioactive B12
- D. Making the client lie down in the supine position for 24-48 hrs after the client has received nonradioactive B12 CARING FOR CLIENTS WITH DISORDERS OF THE HEMATOPOIETIC SYSTEM
Correct Answer: A
Rationale: The correct answer is A because collecting urine 24-48 hrs after the client has received nonradioactive B12 is essential for the Schilling test to evaluate vitamin B12 absorption. Urine is collected to measure the excretion of radioactive B12, which helps in diagnosing pernicious anemia or malabsorption issues.
Incorrect choices:
B: Collecting blood samples is not necessary for the Schilling test as it primarily involves urine collection.
C: Allowing oral fluid consumption is important to prevent dehydration and is not contraindicated after receiving nonradioactive B12.
D: Making the client lie down in the supine position is unnecessary for the Schilling test and may not affect the test results.
Which of the following terms indicates that the patient has a hearing loss caused by aging?
- A. Otoplasty
- B. Presbycusis
- C. Otalgia
- D. Tinnitus
Correct Answer: B
Rationale: The correct answer is B: Presbycusis. Presbycusis refers to age-related hearing loss, commonly affecting higher frequencies. As people age, changes in the inner ear structures can lead to hearing loss. Otoplasty (A) is a surgical procedure to correct ear deformities, not related to aging. Otalgia (C) refers to ear pain, not specifically related to aging. Tinnitus (D) is the perception of ringing or buzzing in the ears, which can occur at any age and is not exclusive to age-related hearing loss.
