Which technique or method is used to determine whether or not the patient has an irregular pulse?

Correct Answer: A

Rationale: An apical pulse check is used to determine if the patient has an irregular pulse. The apical pulse is located at the point of maximal impulse (PMI) and is assessed using a stethoscope. Choice B, inspection, involves visual examination and is not used to assess pulse irregularities. Choice C, auscultation, involves listening to internal sounds using a stethoscope, which can be used to assess heart sounds but not specifically for pulse irregularities. Choice D, percussion, is a technique used to assess the density of body tissues or detect abnormal masses and is not used to determine pulse irregularities.

Correct Answer: C

Rationale: The correct answer is C: Kidney dialysis. A blood potassium level of 9.2 mEq/L indicates severe hyperkalemia, which can be life-threatening. Kidney dialysis is the most appropriate intervention to rapidly lower potassium levels in this situation. Choice A, intravenous potassium supplementation, would worsen the hyperkalemia. Choice B, intravenous calcium supplementation, is not the primary intervention for hyperkalemia. Choice D, parenteral nutrition, is unrelated to treating hyperkalemia and would not address the immediate concern.

Correct Answer: D

Rationale: Even after a patient has expired, standard precautions should be maintained to prevent the spread of infection. Bathing the deceased patient should be done using the same standard precautions followed when the patient was alive. This includes using personal protective equipment and following proper infection control procedures. Choices A, B, and C are incorrect because standard precautions must still be adhered to even after the patient has passed away to ensure safety and prevent the transmission of infections.

Correct Answer: C

Rationale: A computer hacking episode is considered an internal disaster as it disrupts the internal operations of the healthcare facility, compromising data security and potentially impacting patient care. Choices A, B, and D do not directly relate to internal disasters in a healthcare setting. A patient fall is a patient safety issue, the massive spread of pneumonia is a public health concern, and unexpected staff absences due to illness may affect staffing levels but are not typically classified as internal disasters.

Correct Answer: B

Rationale: The correct answer is B. A bivalve cast can help decrease the risk of compartment syndrome by providing space for swelling, thus preventing the build-up of pressure within the muscles. Choices A, C, and D are incorrect because they are not directly related to preventing compartment syndrome. Choice A is more focused on managing heart failure, choice C on reducing intracranial pressure, and choice D on restoring intrathoracic pressure after a pneumothorax, which are not relevant to preventing compartment syndrome.

Correct Answer: A

Rationale: The correct answer is A: 1 in 85 births. The rate of twin pregnancies is approximately 1 in 85 births. This means that twins are more common compared to triplets, which occur at a rate of 1 in 8,100 births. Choices B, C, and D are incorrect because they do not reflect the correct frequency of twin pregnancies as stated in the question.

Correct Answer: D

Rationale: Somogyi effect, also known as rebound hyperglycemia, occurs as a response to nighttime hypoglycemia. Eating a protein and carbohydrate snack at bedtime can help prevent this by stabilizing blood sugar levels throughout the night. Instructing the client to take insulin at 2:00 PM each day (Choice A) may not directly address the nighttime hypoglycemia concern. Engaging in physical activity daily (Choice B) is generally beneficial for diabetes management but may not specifically prevent Somogyi's effect. Increasing the dose of regular insulin (Choice C) without addressing the nighttime hypoglycemia issue can exacerbate the problem.

Correct Answer: C

Rationale: In this scenario, the client with type 1 DM has a high glucose level at bedtime. The appropriate action for the nurse is to administer the sliding scale insulin as ordered. This insulin regimen is specifically designed to manage high blood glucose levels. Calling the physician is not necessary as the protocol for sliding scale insulin is already in place. Encouraging fluid intake or providing orange juice is not the correct intervention for addressing high blood glucose levels in this case.

Correct Answer: D

Rationale: The Moro reflex, also known as the startle reflex, is typically present in infants up to around 4-6 months of age and is characterized by the infant's response to a sudden loss of support or loud noise. It is not a normal finding in adolescents or older individuals. Therefore, if an adolescent patient exhibits the Moro reflex during a neurological assessment, it is considered abnormal and warrants further evaluation. Choices A, B, and C are incorrect because the Moro reflex is not expected or normal among adolescents and does not specifically indicate the status of either the peripheral or central nervous system in this age group.
