1. Which electrolyte imbalance is most likely to cause cardiac arrhythmias?

• A. Hyperkalemia
• B. Hypocalcemia
• C. Hypernatremia
• D. Hypokalemia

Correct answer: A

Rationale: Hyperkalemia is the correct answer as it can lead to dangerous cardiac arrhythmias due to its effects on the electrical conduction of the heart. High levels of potassium can disrupt the normal electrical activity of the heart, potentially leading to life-threatening arrhythmias. Hypocalcemia (choice B) is not the most likely cause of cardiac arrhythmias compared to hyperkalemia. Hypernatremia (choice C), referring to high sodium levels, is not directly associated with causing cardiac arrhythmias. While hypokalemia (choice D), low potassium levels, can also lead to cardiac arrhythmias, hyperkalemia is the more likely culprit in causing severe disturbances in heart rhythm.

2. What disorder closely matches Suzy's symptoms?

• A. Antisocial personality disorder
• B. Borderline personality disorder
• C. Schizoid personality disorder
• D. Dissociative Identity Disorder

Correct answer: B

Rationale: Suzy's symptoms are characteristic of Borderline Personality Disorder (BPD). BPD includes instability in relationships, self-image, and emotions, as well as impulsivity and self-harm. Choice A, Antisocial personality disorder, is characterized by a disregard for others' rights and lack of empathy, which does not align with Suzy's symptoms. Schizoid personality disorder, choice C, is characterized by a lack of interest in social relationships, which is not a prominent feature in Suzy's case. Dissociative Identity Disorder, choice D, involves the presence of two or more distinct identities or personality states, which is not reflected in Suzy's symptoms.

3. You are caring for a patient who just gave birth to a 6 lb. 13 oz. baby boy. The infant gave out a lusty cry, had a pink coloration all over his body, had flexed arms and legs, cried when stimulated, and had a pulse rate of 94. What Apgar score would you expect for this baby?

• A. 10
• B. 8
• C. 7
• D. 9

Correct answer: D

Rationale: The Apgar score is a method used to quickly assess the health of newborns. In this scenario, the baby would receive 2 points for color, reflex irritability, and muscle tone, but only 1 point for a pulse rate of 94, resulting in an Apgar score of 9. An Apgar score of 9 indicates that the baby is in good health overall. Choice A (10) is incorrect because a pulse rate of 94 would only score 1 point. Choices B (8) and C (7) are incorrect as the given criteria would lead to a higher score, indicating the baby's good health.

4. A client who is at full-term gestation is in active labor and complains of a cramp in her leg. Which intervention should the PN implement?

• A. Massage the calf and foot
• B. Elevate the leg above the heart
• C. Check the pedal pulse in the affected leg
• D. Extend the leg and flex the foot

Correct answer: D

Rationale: During labor, muscle cramps are common due to prolonged muscle tension. The correct intervention to alleviate a cramp in the leg is to extend the leg and flex the foot. This action helps relieve the muscle spasm by stretching and contracting the muscles. Massaging the calf and foot (Choice A) may not be as effective in relieving the cramp as extending and flexing the leg. Elevating the leg above the heart (Choice B) is not necessary and may not directly address the cramp. Checking the pedal pulse (Choice C) is important for assessing circulation, but it does not directly address the muscle cramp.

5. According to the principle of asepsis, which situation should the PN consider to be sterile?

• A. A one-inch border around the edges of a sterile field set up in the operating room
• B. A sterile glove that the PN thinks might have touched hair
• C. A wrapped, unopened sterile 4x4 gauze pad placed on a damp table top
• D. An open sterile Foley catheter kit set up on a table at the PN's waist level

Correct answer: A

Rationale: According to the principle of asepsis, the one-inch border around the edges of a sterile field set up in the operating room is considered non-sterile, while the central area remains sterile. Therefore, the PN should consider the situation described in choice A to be sterile. Choice B is incorrect because a glove that may have touched hair is contaminated. Choice C is incorrect as a sterile item placed on a damp surface is considered contaminated. Choice D is incorrect as a sterile kit set up at the PN's waist level is prone to contamination.
