A client in labor has an electronic fetal monitor attached to the abdomen, and the nurse notes that the baby's heart rate slows down during each contraction, returning to normal limits only after the contraction is complete. Which type of fetal heart rate change does this pattern describe?
- A. Variable decelerations
- B. Late decelerations
- C. Early decelerations
- D. Accelerations
Correct Answer: B
Rationale: Late decelerations refer to a pattern where the baby's heart rate decreases during contractions and does not return to normal until after the contraction ends. This is considered a non-reassuring sign as it indicates potential fetal distress. Late decelerations are associated with uteroplacental insufficiency, and immediate medical attention is required. Variable decelerations (Choice A) are abrupt, unpredictable decreases in the fetal heart rate, usually associated with cord compression. Early decelerations (Choice C) are usually benign and mirror the contraction pattern. Accelerations (Choice D) are reassuring signs of fetal well-being, characterized by an increase in the fetal heart rate.

The OR nursing staff are preparing a client for a surgical procedure. The anesthesiologist has given the client medications, and the client has entered the induction stage of anesthesia. The nursing staff can expect which of the following symptoms and activities from the client during this time?
- A. Irregular breathing patterns
- B. Minimal heartbeat, dilated pupils
- C. Relaxed muscles, regular breathing, constricted pupils
- D. Euphoria, drowsiness, dizziness
Correct Answer: D
Rationale: During the induction stage of anesthesia, the client may exhibit symptoms like euphoria, drowsiness, or dizziness. This stage occurs after the administration of medications by the anesthesiologist and ends when the client loses consciousness. Choice A is incorrect as irregular breathing patterns are not typically associated with the induction stage. Choice B is incorrect as minimal heartbeat and dilated pupils are not commonly observed during this stage. Choice C is incorrect as relaxed muscles, regular breathing, and constricted pupils are not indicative of the induction stage of anesthesia.
Which of the following situations might warrant a laboratory magnesium level?
- A. Hyperthyroidism
- B. Arthritis
- C. Ulcerative colitis
- D. Depression
Correct Answer: C
Rationale: Ulcerative colitis can lead to symptoms such as abdominal pain, fever, diarrhea, and weight loss. This condition may impact the absorption of certain nutrients, including magnesium. Therefore, patients with chronic gastrointestinal conditions like ulcerative colitis should be screened for electrolyte imbalances related to impaired digestion. Hyperthyroidism, arthritis, and depression do not typically directly affect magnesium levels in the same way as gastrointestinal conditions like ulcerative colitis.
A client is preparing to give a stool sample for occult blood. All of the following information is part of teaching for this client EXCEPT:
- A. Avoid eating red meat for 3 days before the test
- B. Collect the stool sample from the toilet after having a bowel movement
- C. The stool does not need to be kept in a container with preservative
- D. A small part of the stool from two areas will be tested using a smear
Correct Answer: B
Rationale: When preparing to give a stool sample for occult blood testing, clients need specific instructions to ensure accurate results. It is crucial to educate clients to avoid eating red meat for at least 3 days before the test, as the blood in the meat can interfere with the test results. Clients should be informed that the stool does not need to be kept in a container with preservative as it is not required for this type of testing. Additionally, clients should be aware that a small part of the stool from two areas will be tested using a smear. However, collecting the stool sample from the toilet after having a bowel movement is not recommended as it may introduce contaminants and affect the accuracy of the test. Therefore, this information is not part of the correct teaching for the client preparing to give a stool sample for occult blood.
A client with asthma is being admitted for breathing difficulties. His arterial blood gas results are pH 7.26, PCO2 49, PaO2 90, and HCO3- 21. Which of the following best describes this condition?
- A. Uncompensated respiratory acidosis
- B. Compensated respiratory alkalosis
- C. Uncompensated metabolic acidosis
- D. Compensated metabolic alkalosis
Correct Answer: A
Rationale: In this case, the client's arterial blood gas results show a pH of 7.26 and a PCO2 of 49, both of which are abnormal. A pH below the normal range of 7.35-7.45 indicates acidosis. The elevated PCO2 of 49 mmHg suggests respiratory acidosis as the primary issue. The normal range for PCO2 is 35-45 mmHg, so a value of 49 indicates the retention of excess CO2, leading to acidosis. The low HCO3- level of 21 also supports the presence of metabolic acidosis; however, the primary abnormality is respiratory, making this an uncompensated respiratory acidosis. Therefore, the correct answer is 'Uncompensated respiratory acidosis.'
Choice B, 'Compensated respiratory alkalosis,' is incorrect because the client's pH is acidic, not alkalotic. Additionally, there is no compensation occurring for the primary respiratory acidosis indicated by the elevated PCO2.
Choice C, 'Uncompensated metabolic acidosis,' is incorrect because while the HCO3- level is low, the primary issue indicated by the elevated PCO2 is respiratory acidosis.
Choice D, 'Compensated metabolic alkalosis,' is incorrect since the arterial blood gas results do not support a metabolic alkalosis. The low HCO3- level would typically be seen in metabolic acidosis, but in this case, the primary issue is respiratory acidosis.
While caring for a client who has just come from surgery and is in the recovery room with an endotracheal tube in place, the nurse deflates the cuff on the tube and removes it. The client sits up in bed, grasps his throat, and begins to make wheezing sounds. Which of the following conditions is the most likely cause of this situation?
- A. The client is choking on part of the tube
- B. The client has anxiety
- C. The client is having a laryngospasm
- D. The client is having a normal response from anesthesia
Correct Answer: D
Rationale: After surgery, some clients may experience a laryngospasm during emergence from anesthesia. A laryngospasm can lead to the closure of the laryngeal opening due to spasm of the vocal cords. In this scenario, the client's symptoms of wheezing and throat grasping are indicative of a laryngospasm rather than choking on the tube, anxiety, or a normal response from anesthesia. The nurse should act promptly to open the airway to aid breathing and consider administering muscle relaxants as necessary.
