1.  The nursing process: assess, diagnose, plan, implement, evaluate (ADPIE)

 2.  Nursing is a 24/7 operation that requires teamwork - do your best to prioritize and work safely & pass on the rest.

 3.  Organize tasks by “must do” (within 30 minutes), “should do” (within 4 hours), and “could do” (before end of shift)

 4.  When the number of tasks to be done seems out of control, stop and take a deep breath, even a 5-second break can help!

 5.  Five rights for delegating care: right person, right task, right circumstances, right direction, right supervision

 6.  Take the lead to inspire teamwork - pitch in and help your colleagues. Perhaps others will follow your lead!

 7.  Key to a fulfilling work life…have a goal and focus on working toward it; goal should be realistic & attainable.

 8.  When caring for an abuse victim - establish trusting relationship, treat immediate injuries, record factual account, & refer.

30.  Don't forget common courtesy - introduce yourself to patients and identify yourself as a nurse.

31.  Believe in yourself and your instincts, but always listen to the patient.

32.  Consider asking, "Does anyone have any ethical concerns with this patient's care?" to open dialogue during rounding.

33.  Communication technique - Clarification - For example, "I'm not sure I understood what you said."

34.  Working with students? Offer warm greeting, include in daily routine, treat with respect, and model professional behavior.

35.  To conclude history taking - “I think I have all the information I need now. Is there anything you’d like to add?”

36.  Humor can help put a patient at ease, but avoid sarcasm and keep jokes in good taste. Know where to draw the line.

37.  Closed questions elicit yes/no or 1-2 word answers; can help you zoom in on specific points, but don't allow patient to elaborate.

38.  Good communication is essential when transferring care to another person, speaking with and educating patients, interacting with families and other visitors.

39.  When giving report or transferring care, think SBAR: Situation, Background, Assessment, Recommendation.

40.  Use open-ended questions to assess for abuse: When do you feel safe? When do you not feel safe?

top

41.  Goals of pain management - reduce pain intensity, improve ability to function, improve quality of life.

42.  The goal of pain management is to keep the patient as comfortable as possible. It is not to use as little pain medication as possible.

43.  A patient’s self-report is considered the most accurate way to detect and measure pain.

44.  When choosing a pain rating scale, consider the patient’s visual acuity, age, reading ability, and level of understanding.

45.  Patients with dementia who are in pain may have atypical behaviors (i.e. aggression). Remember: behavioral changes can signal pain.

46.  Don’t expect to find physiologic markers of pain, such as vital sign changes, grimacing, or diaphoresis, in a patient with chronic pain.

52.  When thyroid gland is hypoactive, thyroid stimulating hormone (TSH) level is high; when overactive, TSH level is low.

53.  Myxedema coma occurs when thyroid hormone levels drop too low; thyroid replacement with levothyroxine (T4) is priority.

54.  ABG analysis...pH less than 7.35=acidosis (more Acid), pH greater than 7.45=alkalosis (more Base)...*A* before *B*

55.  Severe or prolonged hypoxemia leads to tissue hypoxia & anaerobic metabolism, altering patient's acid-base status.

56.  pH reflects the concentration of hydrogen ions (H+) in arterial blood. Low pH = more acid (H+) in blood.

57.  The 2 causes of metabolic acidosis you are most likely to see in hospitalized patients: lactic acidosis and ketoacidosis.

 99.  Pericardium is the sac that surrounds the heart and roots of the great vessels; two layers: fibrous pericardium and serous pericardium.

100.  Cardiac output (CO) is the amount of blood the heart pumps in 1 minute. CO= heart rate X stroke volume (amount of blood ejected with each heartbeat).

101.  Stroke volume depends on 3 factors: preload, contractility, and afterload.

102.  Preload = stretching of muscle fibers in the ventricles. This stretching results from blood volume in the ventricles at end-diastole.

103.  Contractility = inherent ability of the myocardium to contract normally; influenced by preload (the greater the stretch, the more forceful the contraction).

104.  Afterload = pressure that the ventricular muscles must generate to overcome the higher pressure in the aorta to get blood out of the heart.

105.  The normal pacemaker of the heart is the sinoatrial (SA) node; generates impulses 60-100 times/minute.

106.  On the horizontal axis of ECG paper, a large block = 0.2 seconds & a small block = 0.04 seconds.

107.  The QRS complex represents ventricular depolarization; it's normally 0.10 second or less.

147.  Crepitus feels like puffed rice cereal crackling under the skin; indicates air leaking from the airways or lungs.

148.  Pre-op teaching for pneumonia prevention - deep breathing, coughing (teach patient to splint), and incentive spirometry.

149.  A decrease in blood pH stimulates the respiratory center, causing hyperventilation. This causes CO₂ to decrease to help normalize pH.

150.  Barrel chest indicates loss of lung elasticity and flattening of diaphragm; seen in patients with COPD.

151.  Pleural space is between visceral pleura (outer lining of lung) and parietal pleura (inner lining of thoracic cavity).

top

165.  Functions of kidneys: form urine to remove wastes from the body, maintain acid-base and fluid-electrolyte balance, and assist in BP control.

166.  The kidneys help manage acid-base balance by regulating bicarbonate concentration of the blood.

167.  The rate of bicarbonate formation by the kidneys is affected by the amount of CO₂ in the blood and the potassium content of the tubular cells.

168.  Kidneys secrete erythropoietin in response to low arterial O₂ tension; it travels to bone marrow to stimulate RBC production.

169.  In renal failure, the kidneys are no longer able to excrete potassium, resulting in hyperkalemia.
