The nurse provides discharge teaching to a patient with sickle cell disease (SCD). Which statements made by the patient indicate understanding of the teaching? (Select all that apply). "I shouldn't receive the pneumococcal injection." "I should drink 2-4 liters of fluid every day." "I should avoid high altitudes." "I should wear socks and gloves when going outside on cold days." "I can safely consume uncooked seafood."

"I should drink 2-4 liters of fluid every day.", "I should avoid high altitudes.", "I should wear socks and gloves when going outside on cold days." Rationale: Patients with SCD should avoid crises by avoiding activities that cause hypoxia. High altitudes can increase the risk for the development of hypoxia. The patient should drink 2-4 liters of fluid every day to avoid dehydration. Eating uncooked seafood increases the risk of infection; this type of product is rich in iron and should be avoided. The pneumococcal injection is recommended to prevent infection. Dress warmly in cold weather to prevent sickling of RBC's in the exposed area.

A patient with chronic kidney disease is most likely to complain of which symptom? A.Fatigue B.Thirst C.Constipation D.Excess bleeding

A. Fatigue

Which occurrence can be a result of hyperventilation? Hypocalcemia Respiratory alkalosis Rationale: Hyperventilation increases blowing out of CO2, resulting in decreased PaCO2 and respiratory alkalosis. Hypocalcemia is not associated with hyperventilation. Anxiety can cause hyperventilation, not the other way around. In metabolic alkalosis, there is an excess of bicarbonate, not decreased PaCO2. Anxiety Metabolic alkalosis

respiratory alkalosis

A. True

Which statement by the nurse when explaining the purpose of positive end-expiratory pressure (PEEP) to the patient's caregiver is accurate? "PEEP prevents the lung air sacs from collapsing during exhalation." "PEEP allows the breathing machine to deliver 100% O2 to the lungs." "PEEP will prevent lung damage while the patient is on the ventilator." "PEEP will push more air into the lungs during inhalation."

"PEEP prevents the lung air sacs from collapsing during exhalation." Rationale: By preventing alveolar collapse during expiration, PEEP improves gas exchange & oxygenation. PEEP will not prevent lung damage, push more air into the lungs, or change the fraction off inspired oxygen (FiO2) delivered to the patient.

A patient with an INR of 2.0. 2. A patient with a platelet count of 80,000. 3. A patient with an aPTT of 41 seconds. 4. A patient with a PT time of 9 seconds.

3. A patient with an aPTT of 41 seconds. Normal aPTT is 30-40 seconds. When a patient is on Heparin the aPTT value, which should be between 1.5-2 times the patients baseline when therapeutic anticoagulation is achieved. The patient would require and increase in heparin dose.

The nurse is administering medications to a client experiencing heart palpitations who is scheduled to receive a dose of furosemide now. Based on the client's laboratory results, what is the nurse's priority actions? Labs: K (2.9), Mg (2.0), Ca (8.9), Na (148) 1. Contact the HCP 2. Conduct a focused cardiac assessment 3. Hold the dose of furosemide 4. Administer a scheduled dose of Metoprolol

3. Hold the dose of furosemide Furosemide decreases the K causing more arrhythmias. Normal K level (3.5-5).

Which order would the nurse perform the interventions listed on the plan of care for a patient with hemophilia who developed bleeding after a fall? 1.Administer prescribed analgesic 2.Rest the knee and pack in ice. 3.Administer specific coagulation factor 4.Encourage mobilization as soon as bleeding ceases.

Which action will the nurse include in the plan of care to maintain the patency of a patient's left arm arteriovenous fistula? Irrigate the fistula site with saline every 8-12 hours. Assess the quality of the left radial pulse. Compare blood pressures in the left and right arms Auscultate for a bruit at the fistula site

Auscultate for a bruit at the fistula site Rationale: The presence of a thrill & bruit indicates adequate blood flow through the fistula. Pulse rate & quality are not good indicators of fistula patency. Blood pressures should never be obtained on the arm with a fistula. Irrigation of the fistula might damage the fistula, & typically only dialysis staff would access the fistula.

When teaching a patient with hemophilia about home management, which of the following is most important for the nurse to include? Avoid contact sports Minimize joint pain by walking Use 325 mg aspirin when severe pain occurs Increase iron-rich foods in the diet

Avoid contact sports Rationale: Patients with hemophilia have a high bleeding risk, so contact sports or other activities that cause tissue injury or bleeding should be avoided. Joint pain may be caused by bleeding in the joints and if this occurs the patient should seek medical care immediately. Iron-rich foods are not appropriate for this, unless they also have an anemia (but still wouldn't be answering the question). Aspirin is normally not used for severe pain and causes bleeding.

Patient takes acetaminophen as needed for pain Patient with several days of vomiting due to food poisoning Patient takes a baby aspirin every day Patient frequently takes calcium carbonate (TUMs) for indigestion.

Patient frequently takes calcium carbonate (TUMs) for indigestion) Rationale: Metabolic alkalosis is caused by either an increase of bases or a decrease of acids. Base excesses are caused by excessive intake of bicarbonates, carbonates, acetates, and citrates. Tums is a calcium carbonate antacid.

The nurse is administering hemodialysis to a patient with chronic kidney disease. For which common complication does the nurse carefully monitor in this patient? Hypotension Hernias Lower back pain Pneumonia

Hypotension Rationale: A rapid removal of fluid results in reduced vascular volume, which can lead to a decreased cardiac output and decreased vascular resistance. Therefore, hemodialysis has the potential to cause hypotension during the process. Peritoneal dialysis is associated with hernias, lower back pain, and pneumonia due to increased intraabdominal pressure while infusing the dialysate and decreased lung expansion caused by frequent upward displacement of the diaphragm.

A client with acute kidney injury has passed the oliguric phase and is producing urine. The creatinine is returning to normal but serum electrolytes are decreased. The nurse identifies which of the following processes as causing the loss of electrolytes? Increasing glomerular filtration rate Decreasing blood urea nitrogen Increasing glomerular permeability Damage to the basement membrane of kidney

Increasing glomerular filtration rate

An adult client with chronic kidney disease tells the nurse they are interested in peritoneal dialysis. Which condition in the client's history causes the nurse to explain that hemodialysis might be a safer option than PD? Appendectomy CHF Chronic HTN Inflammatory bowel disease

Inflammatory bowel disease

Assessment findings of a patient with chronic kidney failure include a glomerular filtration rate (GFR) of 10 mL/min, numbness and burning sensation in the legs, and a blood urea nitrogen (BUN) level of 26 mg/dL. The nurse anticipates that which intervention will be included on the patient's plan of care? Make a referral for dialysis Restrict sodium bicarbonate Administer potassium chloride Provide a magnesium containing antacid.

Make a referral for dialysis Rationale: Dialysis is begun when the patient's uremia can no longer be adequately treated with conservative medical management. Generally, this is when the GFR is less than 15 mL/min. Numbness and burning sensation in the legs are manifestations of peripheral neuropathy caused by nitrogenous waste accumulation in the brain. A patient with a chronic kidney disease (CKD), increased BUN levels, and a very low GFR of 10 mL/min should undergo dialysis to remove nitrogenous wastes and prevent fluid accumulation due to impaired excretion. Potassium is restricted in patients with CKD, high potassium can cause life-threatening changes in cardiac rate and rhythm. Sodium bicarbonate treats metabolic acidosis. A patient with CKD must not take antacids containing magnesium or aluminum because they are excreted by the kidneys.

Which finding is the best indicator that a patient with viral pneumonia is developing acute respiratory distress syndrome (ARDS)? Intercostal retractions noted bilaterally with inspiration Cough productive of thick green mucus Crackling sounds in lung bases No improvement in O2 saturation with increasing oxygen administration

No improvement in O2 saturation with increasing oxygen administration (Rationale: Refractory hypoxemia is the hallmark characteristic of ARDS. Crackles in the lung bases may occur in the early stages of ARDS, but crackles could also be caused by atelectasis or be a symptom of the patient's viral pneumonia. A productive cough is more typical of pneumonia than of ARDS. Intercostal retractions occur with increased work of breathing in ARDS but may also be present with viral pneumonia.)

Which patient who has just arrived in the emergency department will the nurse assess first? The patient who is sitting in tripod position and unable to speak The patient who needs to take a breath after saying five words The patient who is experiences labored breathing with ambulation The patient who reports difficulty sleeping because of dyspnea

The patient who is sitting in tripod position and unable to speak (Use of the tripod position, especially in a patient who is unable to speak because of dyspnea, indicates severe respiratory distress; this patient needs rapid assessment and intervention. A patient who can say 5 words before needing to take a breath may be experiencing mild to moderate respiratory distress and needs assessment, but the patient who is in the tripod position should be assessed first. Nighttime dyspnea needs further assessment for problems such as asthma or obstructive sleep apnea, but this patient is not in any current respiratory distress and can wait to be assessed by the nurse. A patient who experiences labored breathing with ambulation needs assessment but can be asked to rest quietly to decrease work of breathing and does not need immediate assessment or intervention.)

Which intervention would the nurse anticipate incorporating into the plan of care for a patient newly diagnosed with disseminated intravascular coagulation (DIC)? Administer albumin Restrict fluid replacement Treat the causative problem Administer aspirin

Treat the causative problem Rationale: Treating the underlying cause of DIC will interrupt the abnormal response of the clotting cascade and reverse the DIC. Maintenance of organ function is achieved by fluid replacement to sustain adequate circulating blood volume to maintain optimal tissue and organ perfusion. Albumin and aspirin are not interventions for DIC.

Which cardiac dysrhythmia is life threatening and requires immediate intervention? Ventricular fibrillation Sinus bradycardia Atrial fibrillation Sinus tachycardia

Ventricular fibrillation (Rationale: Ventricular fibrillation is a life-threatening dysrhythmia that requires immediate intervention. During ventricular fibrillation, the ventricles are quivering and no longer able to contract to produce effective cardiac output. Because there is no cardiac output, the body is left without oxygenation. Sinus tachycardia requires treatment to slow the rate to 60 to 100 beats/min. Atrial fibrillation requires treatment to convert the rhythm back to a normal sinus rhythm with one atrial contraction for every ventricular contraction. Sinus bradycardia has a normal sinus rhythm, but rate is <60/minute. It may be a normal condition. Only those with symptoms receive treatment.)

What two minerals are dependent for coagulation cascade

calcium and vitamin K

A patient newly diagnosed with chronic renal failure recently has begun hemodialysis. Knowing that the patient is at risk for disequilibrium syndrome, the nurse assesses the patient during dialysis for: a. Hypertension, tachycardia, and fever b. Hypotension, bradycardia, and hypothermia c. Pain, dizziness, and generalized weakness d. Headache, deteriorating level of consciousness, and twitching

d. Headache, deteriorating level of consciousness, and twitching
