1. A 22-year-old patient in a mental health lock-down unit under suicide watch appears happy about being discharged. Which of the following is probably happening?
- A. The patient is excited about being around family again.
- B. The patient's suicide plan has probably progressed.
- C. The patient's plans for the future have been clarified.
- D. The patient's mood is improving.
Correct answer: B
Rationale: In this scenario, it is concerning that a patient under suicide watch is happy about being discharged as it may indicate that the patient's suicide plan has advanced. This change in behavior should be taken seriously as it can signal an increased risk of self-harm. Choices A, C, and D are less likely as the patient's happiness about discharge in this context is more indicative of a worsening situation rather than positive outcomes like being around family, clarifying future plans, or improving mood.
2. 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.
3. Which action by a graduate nurse would require the charge nurse to intervene?
- A. Walking in the hallway outside the operating room without a hair covering
- B. Putting on a surgical mask, gown, and cap before entering the operating room
- C. Wearing a surgical mask into the holding area
- D. Wearing scrubs from home into the nursing station
Correct answer: A
Rationale: The correct answer is walking in the hallway outside the operating room without a hair covering. In healthcare settings, it is crucial to adhere to infection control measures, which include wearing appropriate attire to prevent the spread of pathogens. Walking in the hallway outside the operating room without a hair covering violates these infection control protocols, necessitating immediate intervention by the charge nurse. Choices B and C are incorrect because putting on surgical attire before entering the operating room and wearing a surgical mask into the holding area are both standard practices that promote patient safety and infection control. Choice D is also incorrect as wearing scrubs from home into the nursing station, while not ideal, is not a violation that warrants immediate intervention compared to breaching infection control protocols near sensitive areas like the operating room.
4. A client with asthma develops respiratory acidosis. Based on this diagnosis, what should the nurse expect the client's serum potassium level to be?
- A. normal
- B. elevated
- C. low
- D. unrelated to the pH
Correct answer: B
Rationale: In respiratory acidosis, the body retains CO2, leading to increased hydrogen ion concentration and a drop in blood pH. As pH decreases, serum potassium levels increase due to the movement of potassium out of cells to compensate for the acidosis. Elevated serum potassium levels are expected in respiratory acidosis. Choice A ('normal') is incorrect because potassium levels are expected to be elevated in respiratory acidosis. Choice C ('low') is incorrect as potassium levels rise in this condition. Choice D ('unrelated to the pH') is incorrect as serum potassium levels are directly impacted by changes in pH in respiratory acidosis.
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.
