1. A newborn baby exhibits a reflex that includes hand opening, abducted, and extended extremities following a jarring motion. Which of the following correctly identifies the reflex?
- A. ATNR reflex
- B. Startle reflex
- C. Grasping reflex
- D. Moro reflex
Correct answer: D
Rationale: The Moro reflex, also known as the startle reflex, is the correct answer. This reflex is characterized by the baby's response to a sudden head movement or loud noise, causing them to open their hands, extend their arms, and then bring them back towards their body. The characteristics mentioned in the question - hand opening, abducted, and extended extremities following a jarring motion - align with the Moro reflex. The asymmetrical tonic neck reflex (ATNR) involves the head turning to one side with extension of the same side's arm and leg, not the described characteristics. The grasping reflex involves the baby's response to touch on the palm, causing them to grasp an object. While the Moro reflex is often referred to as the startle reflex due to its response to sudden stimuli, the specific characteristics described in the question match the Moro reflex.
2. To determine the standards of care for the institution, the nurse should consult?
- A. Organizational Chart
- B. Personnel policies
- C. Policies and procedure manual
- D. Job descriptions
Correct answer: C
Rationale: The correct answer is the 'Policies and procedure manual.' This manual outlines the policies and procedures that govern patient care within the institution, including the standards of care that healthcare providers are expected to follow. Consulting the policies and procedure manual ensures that the nurse is adhering to the established guidelines and protocols. Choices A, B, and D are incorrect because although they are important documents within an institution, they do not specifically define the standards of care for patient management. The organizational chart illustrates the hierarchy of the institution, personnel policies outline rules related to employees, and job descriptions detail specific roles and responsibilities, none of which directly define patient care standards.
3. 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.
4. A nurse is caring for a client with an elevated urine osmolarity. The nurse should assess the client for:
- A. fluid volume excess.
- B. hyperkalemia.
- C. hypercalcemia.
- D. fluid volume deficit.
Correct answer: D
Rationale: Elevated urine osmolarity indicates that the urine is concentrated, suggesting the body is trying to conserve water. This commonly occurs in conditions like dehydration or fluid volume deficit. Assessing the client for fluid volume excess, hyperkalemia, or hypercalcemia would not be the priority in this situation. Therefore, the correct answer is to assess the client for fluid volume deficit. Fluid volume excess is characterized by decreased urine osmolarity, while hyperkalemia and hypercalcemia are related to electrolyte imbalances and would not directly cause elevated urine osmolarity.
5. The nurse is caring for a client with hyperemesis gravidarum. What is the most likely electrolyte imbalance?
- A. Hypocalcemia
- B. Hypomagnesemia
- C. Hyponatremia
- D. Hypokalemia
Correct answer: D
Rationale: In hyperemesis gravidarum, where the client experiences severe nausea and vomiting, the most likely electrolyte imbalance is hypokalemia. Potassium is abundant in the stomach, and excessive vomiting leads to potassium loss. Hypocalcemia (Choice A) is not typically associated with hyperemesis gravidarum. Hypomagnesemia (Choice B) and Hyponatremia (Choice C) are less likely to occur compared to hypokalemia in this condition.
