NCLEX-RN EXAM REVIEW QUESTIONS AND ANSWERS 100% CORRECT When selecting an NCLEX answer or determining the order of priority what should you remember or use and what is the exception? - Use the ABC rule: Airway breathing, and circulation. The exception to the rule is with actual CPR, use C-A-B for CPR. Also remember safety first and acute before chronic. If the pt. is not in distress then you assess. If the pt is in distress then you should do something. If the pt has diaphorisis you should always do something. How should you address questions related to Maslow's Hierarchy of Needs - Address physiological needs first, followed by safety and security needs, love and belonging needs, self esteem needs and finally self actualization needs. *When a physiological need is not addressed in the question, look for the option that addresses safety. If a question is related to the nursing process, read the question to determine the step of the nursing process. What are the steps in the nursing process and what kind of question might be related to that step. - Assessment question address the gathering and verification of data. Analysis questions require the nurse to: interpret data, collect additional information, identify and communicate nursing diagnoses and determine the health team's ability to meet the pts needs. Planning questions ask about determining, prioritizing, and modifying outcomes of care. Implementation questions reflect the management and organization of care and the assignment and delegation of tasks. Be prepared for questions on client teaching. Evaluation questions focus on comparing the actual outcomes of care with the expected outcomes and on communicating and documenting findings. What are the normal ranges for H&H?

It is a careless act of omission or commission that results in injury to another. What is nursing malpractice? - Malpractice is not always negligence. It is often referred to as professional negligence, it is a type of negligence. It is the failure to use that degree of care that a reasonable nurse would use under the same or similar circumstances. Malpractice is found when: *The nurse owed a duty to the patient *The nurse did NOT carry out the duty/breached that duty *The patient was at a high risk of injury * The nurse's failure to carry out that duty caused the patients injury Where do Standards of Care originate? - Nurses are required to follow standards of care, which originate in the Nurse Practice Acts, state and federal laws, accreditation recommendations, the guidelines of professional organizations, and the written policies and procedures of the healthcare agency What are nurses responsible for related to the standards of care? - Nurses are responsible for performing procedures correctly and exercising professional judgment when implementing healthcare providers prescriptions. When can the nurse NOT follow the healthcare provider's prescription and what must they do about it? - Nurses MUST follow the healthcare provider's prescription unless the nurse believes that it is in error; that it violates hospital policy; or that it is harmful to the patient. The nurse makes a formal report explaining the refusal. The nurse should file an incident (occurrence) report for any situation that may result in harm to the patient. What should the nurse do related to advanced medical directives (ADs) - Assess the patients knowledge of advance directives.

Many Chinese Americans are uncomfortable with face-to-face communications, especially when eye contact is direct. If the client turns away from the nurse during a conversation, the best action is to continue with the conversation. Walking around the client so that the nurse faces the client is in direct conflict with this cultural practice. The client may consider it a rude gesture if the nurse returns later to continue with the explanation. Telling the client about the importance of the instructions for the maintenance of health care may be viewed as degrading. What are low risk therapies - Low-risk therapies are therapies that have no adverse effects and, when implementing care, can be used by the nurse who has training and experience in
their use. Low-risk therapies include meditation, relaxation techniques, imagery, music therapy, massage, touch, laughter and humor, and spiritual measures, such as prayer.

Asian Americans have a lower risk for obesity and diabetes mellitus. Define fluid volume excess: Hypervolemia - too much fluid in the vascular space (first). Vascular equals the vessels --> veins, arteries, capillaries, heart chambers, etc. What can cause fluid volume excess: Hypervolemia - Heart Failure (HF) where the heart is weak, CO is decreased, the kidneys have decreased perfusion and urinary output is decreased. **The volume stays in the vascular space! Renal Failure (RF) When the kidneys are not working. Medications: alka-seltzer, fleet enema's and IVF with Na. These medications have a lot of sodium causing water retention in the vascular space. What are the two main hormonal regulations related to fluid volume - Aldosterone (steroid, mineralocorticoid) Atrial Natriuretic Peptide (ANP) Where is aldosterone found - in the adrenal glands When blood volume gets low (vomiting, blood loss, etc.) what happens to the secretion of aldosterone and what happens because of it? - Aldosterone secretion increases which causes a retention of sodium and water which will make blood volume go up or increase. What diseases are related to too much aldosterone? - Cushings and Hyperaldosteronism (Conn's) Which disease is related to not enough aldosterone? - Addisons: fluid volume is decreased Where is Atrial Natriuretic Peptide (ANP) found? - In the atria of the heart How does atrial natriuretic peptide (ANP) work? - It is the opposite of aldosterone, so it causes excretion of Nas and H2O aminoglycosides (mycins) -
