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.

A client has been receiving cyanocobalamin (B12) injections for the past 6 weeks. Which laboratory finding indicates that the medication is having the desired effect?
- A. Neutrophil count of 60%
- B. Basophil count of 0.5%
- C. Monocyte count of 2%
- D. Reticulocyte count of 1%
Correct Answer: D
Rationale: Cyanocobalamin is a B12 medication used for pernicious anemia. A reticulocyte count of 1% indicates the desired effect of the medication, as reticulocytes are immature red blood cells that increase in response to B12 therapy, improving anemia. Neutrophils, basophils, and monocytes are white blood cells and are not directly influenced by B12 injections, making them incorrect choices.
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.
What is the preferred position for a client post liver biopsy procedure?
- A. Fowler's
- B. Right side
- C. Left side
- D. Prone
Correct Answer: B
Rationale: The correct position for a client post liver biopsy procedure is the right side. Placing the client on the right side helps apply pressure to the liver area, which can help in holding pressure and stopping bleeding. Placing the client on the left side may not be as effective in providing direct pressure on the liver. The prone position is also not ideal for post-liver biopsy care as it does not target the liver area directly. Fowler's position, a semi-sitting position, is not typically recommended post liver biopsy as it does not provide the necessary pressure on the liver site.
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.
A woman is in the active phase of labor. An external monitor has been applied, and a fetal heart deceleration of uniform shape is observed, beginning just as the contraction is underway and returning to the baseline at the end of the contraction. Which of the following nursing actions is most appropriate?
- A. Administer O2 if necessary.
- B. Turn the client on her left side.
- C. Notify the physician.
- D. No action is necessary.
Correct Answer: D
Rationale: The correct answer is 'No action is necessary.' In this scenario, the fetal heart deceleration of uniform shape observed is an early deceleration resulting from head compression. Early decelerations are benign and typically do not require any intervention as they mirror the contraction pattern. It is essential to closely observe both the mother and the baby. Administering O2 (Choice A) is not necessary as early decelerations do not indicate fetal distress. Turning the client on her left side (Choice B) is not required for early decelerations. Notifying the physician (Choice C) is not needed for this type of deceleration, as it is a normal response to head compression during labor.
