Which of the following findings should indicate to the nurse that the client is experiencing orthostatic hypotension?
A. The client's heart rate increases by 10/min.
An increase in heart rate by 10 beats per minute when moving from a supine to a sitting position is a normal physiological response to compensate for decreased venous return and maintain cardiac output. This response does not indicate orthostatic hypotension.
B. The client's diastolic blood pressure increases by 10 mm Hg.
An increase in diastolic blood pressure by 10 mm Hg when moving from a supine to a sitting position is a normal response to compensate for the effects of gravity on blood flow. It helps maintain perfusion to vital organs and does not indicate orthostatic hypotension.
C. The client reports heart palpitations.
Heart palpitations can occur due to various reasons, including anxiety or arrhythmias, but they are not specific signs of orthostatic hypotension. This symptom alone does not confirm the presence of orthostatic hypotension.
D. The client's systolic blood pressure decreases by 25 mm Hg.
A decrease in systolic blood pressure by 25 mm Hg or more when moving from a supine to a sitting position indicates orthostatic hypotension. Orthostatic hypotension is defined as a drop in systolic blood pressure of 20 mm Hg or more or a drop in diastolic blood pressure of 10 mm Hg or more within 3 minutes of standing up. This condition can cause dizziness, lightheadedness, or fainting and can be a side effect of antihypertensive medications or other underlying medical conditions.

Full Explanation
Choice A rationale:
An increase in heart rate by 10 beats per minute when moving from a supine to a sitting position is a normal physiological response to compensate for decreased venous return and maintain cardiac output. This response does not indicate orthostatic hypotension.
Choice B rationale:
An increase in diastolic blood pressure by 10 mm Hg when moving from a supine to a sitting position is a normal response to compensate for the effects of gravity on blood flow. It helps maintain perfusion to vital organs and does not indicate orthostatic hypotension.
Choice C rationale:
Heart palpitations can occur due to various reasons, including anxiety or arrhythmias, but they are not specific signs of orthostatic hypotension. This symptom alone does not confirm the presence of orthostatic hypotension.
Choice D rationale:
A decrease in systolic blood pressure by 25 mm Hg or more when moving from a supine to a sitting position indicates orthostatic hypotension. Orthostatic hypotension is defined as a drop in systolic blood pressure of 20 mm Hg or more or a drop in diastolic blood pressure of 10 mm Hg or more within 3 minutes of standing up. This condition can cause dizziness, lightheadedness, or fainting and can be a side effect of antihypertensive medications or other underlying medical conditions.

A nurse is assessing a child who is postoperative following a tonsillectomy.
Which of the following findings should the nurse identify as the priority?
A. Sore throat.
A sore throat is a common and expected finding after a tonsillectomy due to irritation from the procedure. While it can cause discomfort, it is not a priority concern unless it worsens significantly or is accompanied by other symptoms indicating complications such as bleeding or infection.
B. Frequent swallowing.
Frequent swallowing can be a sign of bleeding after a tonsillectomy. The child may swallow more often to clear blood or blood clots from the throat, which could indicate that there is active bleeding from the surgical site.
C. Blood-tinged mucus.
Blood-tinged mucus is a common finding in the immediate postoperative period after a tonsillectomy. It is expected due to the healing process and is not a cause for concern unless it becomes profuse or is accompanied by active bleeding.
D. Dark brown emesis.
While dark brown vomit may indicate that the child has swallowed blood, it is not as immediately concerning as frequent swallowing, which could suggest active bleeding at the surgical site. Dark brown emesis is typically less alarming, but it should still be monitored closely.

A nurse is teaching a client who is pregnant about nonstress testing.
Which of the following statements by the client indicates an understanding of the teaching?
A. "I will get oxytocin during this test.”
Oxytocin is not typically administered during a nonstress test. Oxytocin is a hormone that induces or augments labor contractions; it is not used in nonstress testing, which monitors fetal heart rate and movement. The administration of oxytocin during nonstress testing would not be appropriate or necessary.
B. "During this test, I must not eat or drink anything.”
Fasting is not required for a nonstress test. Nonstress testing involves attaching electronic fetal monitors to the mother's abdomen to measure the baby's heart rate and movement. It does not require the patient to abstain from eating or drinking. Imposing unnecessary restrictions on the client's diet could cause discomfort and anxiety, which is not conducive to an accurate assessment.
C. "This test will tell me if my baby has a genetic problem.”
Nonstress testing is used to evaluate the baby's heart rate response to its own movements. It does not diagnose genetic problems. Genetic testing, such as amniocentesis or chorionic villus sampling, is a different type of test used to detect genetic abnormalities in the fetus. Therefore, this statement does not reflect an understanding of the purpose of nonstress testing.
D. "During this test, I will push a button if my baby moves.”
This is the correct answer. Nonstress testing involves monitoring the baby's heart rate and movement. During the test, the mother pushes a button when she feels the baby move. This allows the healthcare provider to correlate fetal movements with changes in the baby's heart rate. An understanding of this process indicates that the client comprehends the purpose and procedure of the nonstress test.

A nurse is teaching a class about providing care within the legal scope of practice to a group of nurses.
The nurse should include that which of the following procedures is outside the legal scope of practice for an RN?
A. Changing the inner cannula on a tracheostomy.
Changing the inner cannula on a tracheostomy is within the legal scope of practice for registered nurses. Nurses are trained to perform tracheostomy care, including changing the inner cannula. This procedure is within the nursing scope of practice and does not require a physician's intervention.
B. Inserting a tunneled central venous catheter.
InseInserting a tunneled central venous catheter (such as a Hickman line) is a specialized procedure that generally falls under the scope of practice for advanced practice nurses (such as nurse practitioners or clinical nurse specialists) or physicians. RNs typically do not have the required training or authority to perform this invasive procedure.
C. Irrigation of an external ear canal.
Irrigation of an external ear canal is within the legal scope of practice for registered nurses. Ear irrigation is a common nursing procedure used to remove impacted cerumen (earwax) and foreign bodies from the ear canal. Nurses are trained to perform this procedure safely and effectively.
D. Administering a platelet transfusion.
Administering blood products, including platelet transfusions, is within the legal scope of practice for an RN. RNs are responsible for preparing, verifying, and administering blood products according to institutional policies and procedures. This includes monitoring the patient during and after the transfusion for any adverse reactions.
