Correct Answer: B

Rationale: When a blood pressure cuff is too wide for a client's arm, it may produce an abnormally low blood pressure reading. This occurs because the oversized cuff can lead to an underestimation of blood pressure. It is essential to ensure that the cuff fits appropriately to obtain an accurate reading. An abnormally high reading (Choice C) is less likely with an oversized cuff, as it generally leads to lower readings. A normal reading (Choice A) is unlikely due to the inaccuracies caused by the oversized cuff. A fluctuating reading (Choice D) is not a typical result of using a cuff that is too wide; instead, it usually leads to consistently low readings.

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.

Correct Answer: D

Rationale: When assessing blood pressure by palpation, it is important to note that only the systolic blood pressure can be determined accurately using this method. Diastolic blood pressure cannot be reliably assessed through palpation. The palpation technique is particularly useful in situations where traditional blood pressure measurement methods are challenging, such as in infants, small children, or individuals with low blood pressure that is difficult to hear. Hypertension, a common condition characterized by elevated blood pressure, is typically assessed using auscultation rather than palpation. Therefore, the correct statement is that only the systolic blood pressure can be assessed through palpation.

Correct Answer: B

Rationale: Late decelerations are characterized by the baby's heart rate declining in utero during contractions. The heart rate drops below baseline and stays low until after the contraction ends. Late decelerations are concerning as they indicate uteroplacental insufficiency, which can compromise fetal oxygenation. This pattern is a non-reassuring sign and requires immediate intervention. Variable decelerations are typically abrupt decreases in heart rate, often associated with cord compression. Early decelerations, on the other hand, mirror the contractions and are considered benign, resulting from fetal head compression. Accelerations are reassuring signs of fetal well-being, indicating a responsive and healthy fetal nervous system.

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.
