Nokea
The nurse is caring for a client complaining of intense headaches with increasing pain for the past one month. An MRI is ordered. In reviewing the client's information, which piece of information is of concern?
- A. Allergy to shellfish
- B. Has a cardiac pacemaker
- C. A diabetic
- D. No IV access
Correct Answer: B
Rationale: The correct answer is 'Has a cardiac pacemaker.' If a client with a cardiac pacemaker undergoes an MRI, the magnetic field can interfere with the pacemaker's function, leading to serious complications or even death. It is crucial to ensure that the pacemaker is compatible with MRI imaging or to consider alternative imaging modalities. The other choices, such as 'Allergy to shellfish,' 'A diabetic,' and 'No IV access,' are not direct contraindications for an MRI scan and do not pose the same level of risk as having a cardiac pacemaker.

One week ago, a client was involved in a motor vehicle crash (MVC) and was brought to the Emergency Department (ED). In the emergency department, the client received two stitches to the forehead and was sent home. Today, the client's spouse notes that the client 'acts like he is drunk' and cannot control his right foot and arm. The nurse will suspect?
- A. Meningitis
- B. Absence seizure
- C. Subdural hematoma
- D. Meniere's disease
Correct Answer: C
Rationale: Yes! The nurse will suspect a subdural hematoma. In this case, the client's presentation of acting intoxicated and experiencing loss of motor control in the right foot and arm is indicative of an acute subdural hematoma. This condition can occur after a head injury with a slow venous bleed, where symptoms may not show until compensation mechanisms are overwhelmed. Meningitis (choice A) usually presents with fever, headache, and neck stiffness. Absence seizure (choice B) is characterized by brief periods of unconsciousness without convulsions. Meniere's disease (choice D) manifests with symptoms like vertigo, hearing loss, and tinnitus, which do not match the client's current symptoms.
When preparing a client for platelet pheresis in the blood bank, which information is most significant to obtain during the history assessment?
- A. Allergies to shellfish
- B. Date of last platelet donation
- C. Time of last oral intake
- D. Blood type
Correct Answer: B
Rationale: The most significant information to gather when a client is scheduled for platelet pheresis is the date of their last platelet donation. Platelet donors can typically have their platelets apheresed as frequently as every 14 days. Knowing the date of the last donation helps ensure the client is eligible for the procedure without risking any adverse effects from frequent donations. Allergies to shellfish may be important for other procedures where anticoagulants containing heparin are used, but it is not directly related to platelet pheresis. The time of the last oral intake is more crucial for procedures requiring sedation or anesthesia. Blood type is significant for blood transfusions but is not the primary concern for platelet pheresis.
Which hormone is responsible for amenorrhea in the pregnant woman?
- A. Progesterone
- B. Estrogen
- C. Follicle-stimulating hormone (FSH)
- D. Human chorionic gonadotropin (hCG)
Correct Answer: A
Rationale: Correct! Progesterone is the hormone responsible for amenorrhea in pregnant women. Progesterone plays a crucial role in maintaining the uterine lining for implantation and supporting early pregnancy. High levels of progesterone during pregnancy suppress the normal menstrual cycle, leading to amenorrhea. Estrogen, FSH, and hCG do not directly cause amenorrhea in pregnant women. Estrogen is involved in the development of female secondary sexual characteristics, FSH is involved in the growth and maturation of ovarian follicles, and hCG is produced by the placenta to support the production of progesterone during pregnancy.
Which is an example of a sentinel event?
- A. The terminally ill client is referred to hospice and dies 3 months later.
- B. A client receives an unordered mammogram which reveals a small cyst.
- C. A client with a laceration to the knee requiring 4 sutures falls when getting up unassisted after being instructed to remain in bed.
- D. A client scheduled for knee replacement surgery had an above-the-knee amputation performed.
Correct Answer: D
Rationale: Yes! A sentinel event is an unexpected occurrence causing death or serious injury. In this case, a client who was scheduled for knee replacement surgery but had an above-the-knee amputation performed instead represents a sentinel event as it resulted in serious harm that was not intended. The other choices do not meet the criteria for a sentinel event. Choice A describes a natural progression for a terminally ill client, choice B shows an incidental finding from a test, and choice C involves a preventable fall leading to an injury but not a sentinel event.
A 70-year-old male who is recovering from a stroke exhibits signs of unilateral neglect. Which behavior is suggestive of unilateral neglect?
- A. The client is observed shaving only one side of his face.
- B. The client is unable to distinguish between two tactile stimuli presented simultaneously.
- C. The client is unable to complete a range of vision without turning his head side to side.
- D. The client is unable to carry out cognitive and motor activity at the same time.
Correct Answer: A
Rationale: Unilateral neglect is a condition where a person ignores one side of their body. In this case, the behavior of shaving only one side of the face indicates neglect of the other side. This behavior is suggestive of unilateral neglect as the individual is failing to attend to one side of their body. Choices B, C, and D are not associated with unilateral neglect. Choice B refers to tactile agnosia, a condition where a person cannot recognize objects by touch, not related to ignoring one side of the body. Choice C describes a visual field cut, which is a different visual deficit. Choice D relates to dual-task interference, not specific to ignoring one side of the body.
