An infant experienced an apparent life-threatening event (ALTE) and is being placed on home apnea monitoring. Parents have understood the instructions for use of a home apnea monitor when they state?

  • A. "We can adjust the monitor to eliminate false alarms."
  • B. "We should sleep in the same bed as our monitored infant."
  • C. "We will check the monitor several times a day to be sure the alarm is working."
  • D. "We will place the monitor in the crib with our infant."
Correct Answer: C

Rationale: The correct statement indicating understanding of the instructions for use of a home apnea monitor is "We will check the monitor several times a day to be sure the alarm is working." This is important because regular monitoring of the device's functioning ensures that it is able to detect any potential apnea episodes or abnormalities in the infant's breathing patterns. Checking the monitor several times a day helps in maintaining the safety and effectiveness of the monitor in alerting the parents to any potential issues with the infant's breathing. The other options are incorrect: A is incorrect because adjusting the monitor to eliminate false alarms can compromise its accuracy, B is incorrect as the infant should sleep in a separate safe sleep environment to reduce the risk of SIDS, and D is incorrect as the monitor should be placed near the infant's crib but not directly in it for safety reasons.

The nurse is reviewing the patient's daily PT and INR levels. The PT level is 26 (normal = 9 to 12 seconds). Which of the ff. actions should the nurse take?

  • A. Give the next dose of warfarin when it is ordered to be given.
  • B. Inform physician before the next dose of warfarin is given. c.Stop the heparin infusion.
  • C. Continue monitoring heparin infusion.
Correct Answer: B

Rationale: A PT level of 26 seconds is significantly above the normal range of 9 to 12 seconds. This indicates that the patient's blood is taking much longer to clot than usual, which may put the patient at risk for bleeding. It is important for the nurse to inform the physician before giving the next dose of warfarin because warfarin is a medication that helps prevent blood clots by thinning the blood. However, in this case, the patient's blood is already thin beyond the target range, so giving the next dose of warfarin without physician guidance may further increase the risk of bleeding. The physician may need to adjust the dose or recommend other interventions to manage the patient's PT levels effectively.

Mrs. Zeno asks the nurse why the disease has occurred. The nurse bases the reply on the knowledge that there is:

  • A. A genetic defect in the production of acetylcholine
  • B. A reduced amount of neurotransmitter acetylcholine
  • C. A decreased number of functioning acetyl-choline receptor sites
  • D. An inhibition of the enzyme Ache leaving the end plates folded.
Correct Answer: C

Rationale: The disease mentioned in the question is likely myasthenia gravis. Myasthenia gravis is an autoimmune disorder where the body's immune system attacks acetylcholine receptors at the neuromuscular junction. Acetylcholine is a neurotransmitter responsible for transmitting nerve impulses to muscles. In myasthenia gravis, the immune system destroys or blocks the acetylcholine receptor sites on muscle cells, leading to a decrease in the number of functioning receptor sites. This results in muscle weakness and fatigue because the communication between nerves and muscles is impaired. This is why the nurse would base the reply on the knowledge that there is a decreased number of functioning acetyl-choline receptor sites as the underlying cause of the disease.

When assessing a client with a disorder of the hematopoietic or the lymphatic, why is it important for the nurse to obtain a dietary history?

  • A. Compromised nutrition interferes with the production of blood cells and hemoglobin
  • B. Diet consisting of excessive fat interferes with the production of blood cells and haemoglobin
  • C. Inconsistent dieting interferes with the production of blood cells and haemoglobin
  • D. Diet consisting of excessive iron and protein elements interferes with the production of blood cells and haemoglobin
Correct Answer: A

Rationale: When assessing a client with a disorder of the hematopoietic or lymphatic system, obtaining a dietary history is important because compromised nutrition can interfere with the production of blood cells and hemoglobin. Hematopoiesis, the process of blood cell formation, requires adequate nutrition to support the production of red and white blood cells, as well as platelets. Nutrient deficiencies, such as iron, vitamin B12, and folate, can lead to anemia, which affects the oxygen-carrying capacity of red blood cells. Therefore, understanding the client's dietary intake can help the nurse identify any potential deficiencies or excessive intake that may be impacting hematopoiesis.

All the following are compatible with the definition of obstructive sleep apnea EXCEPT

  • A. episodes of prolonged upper airway obstruction
  • B. repeated apnea
  • C. 230% reduction in airflow
  • D. 2-30% O2 desaturation
Correct Answer: D

Rationale: Oxygen desaturation of 2-30% is too low to define mild-to-moderate sleep apnea.

The major manifestation of nephrotic syndrome is:

  • A. hematuria.
  • B. hyperalbuminemia.
  • C. edema.
  • D. anemia.
Correct Answer: C

Rationale: The major manifestation of nephrotic syndrome is edema. Nephrotic syndrome is a kidney disorder characterized by increased permeability of the glomerular filtration barrier, leading to excessive protein loss in the urine. This results in low levels of protein in the blood, particularly albumin, leading to a decrease in oncotic pressure. The decreased oncotic pressure causes fluid to accumulate in the interstitial spaces, leading to edema formation. Patients with nephrotic syndrome typically present with periorbital edema, pedal edema, and ascites due to the fluid redistribution in the body. Hematuria, hyperalbuminemia, and anemia are not typically the primary manifestations of nephrotic syndrome.
