The nurse is instructing the client on the correct way to take nitroglycerin as needed for chest pain:
A. Two tablets PO (by mouth) every 15 minutes.
Taking two tablets PO every 15 minutes is not the standard protocol for nitroglycerin administration for chest pain. This method could lead to an overdose and significant hypotension (low blood pressure), which can be dangerous.
B. One tablet SL (sublingual) every 15 minutes, up to 5 times.
One tablet SL every 15 minutes, up to 5 times, is also not the standard protocol. While sublingual administration is correct, the frequency and the total number of doses are higher than recommended, which could result in adverse effects such as headache, dizziness, or a severe drop in blood pressure.
C. One tablet PO (by mouth) every one hour, up to 5 times.
One tablet PO every one hour, up to 5 times, is not a recommended method for acute chest pain relief from angina. Oral administration does not provide the rapid onset of action required for acute angina relief.
D. One tablet SL (sublingual) every 5 minutes, up to 3 times.
One tablet SL every 5 minutes, up to 3 times, is the correct protocol for nitroglycerin administration when experiencing chest pain due to angina. If pain persists after the first dose, the patient can take a second dose after 5 minutes, and if needed, a third dose after another 5 minutes. If chest pain continues after three doses in 15 minutes, emergency medical help should be sought immediately.

Full Explanation
Choice A reason: Taking two tablets PO every 15 minutes is not the standard protocol for nitroglycerin administration for chest pain. This method could lead to an overdose and significant hypotension (low blood pressure), which can be dangerous.
Choice B reason: One tablet SL every 15 minutes, up to 5 times, is also not the standard protocol. While sublingual administration is correct, the frequency and the total number of doses are higher than recommended, which could result in adverse effects such as headache, dizziness, or a severe drop in blood pressure.
Choice C reason: One tablet PO every one hour, up to 5 times, is not a recommended method for acute chest pain relief from angina. Oral administration does not provide the rapid onset of action required for acute angina relief.
Choice D reason: One tablet SL every 5 minutes, up to 3 times, is the correct protocol for nitroglycerin administration when experiencing chest pain due to angina. If pain persists after the first dose, the patient can take a second dose after 5 minutes, and if needed, a third dose after another 5 minutes. If chest pain continues after three doses in 15 minutes, emergency medical help should be sought immediately.

A client with a spinal cord injury is at risk for experiencing autonomic dysreflexia. The nurse would carefully monitor the client for which of the following manifestations?
A. Severe, throbbing headache
A severe, throbbing headache is a common and significant manifestation of autonomic dysreflexia. This condition is a potentially life-threatening medical emergency that can occur in individuals with spinal cord injuries, typically above the T6 level. The headache results from a sudden and severe increase in blood pressure due to an exaggerated response of the autonomic nervous system to a stimulus below the level of the injury.
B. Hypotension
Hypotension, or low blood pressure, is not a manifestation of autonomic dysreflexia. In fact, the condition is characterized by hypertension, or high blood pressure, which is a critical sign that requires immediate attention to prevent complications such as stroke or seizure.
C. Fever
Fever is not a direct manifestation of autonomic dysreflexia. While a fever may indicate an infection or other systemic issue, autonomic dysreflexia itself is specifically associated with a rapid onset of high blood pressure and other autonomic disturbances.
D. Cyanosis of the head and neck
Cyanosis of the head and neck, which refers to a bluish discoloration of the skin due to poor circulation or inadequate oxygenation of the blood, is not a typical manifestation of autonomic dysreflexia. The condition primarily causes hypertension and its associated symptoms, rather than issues with oxygenation.

A patient is exhibiting an altered level of consciousness and is unresponsive to verbal stimuli. To elicit a response from a painful stimulus, the nurse would:
A. Press down on the orbital area of the eye.
Pressing down on the orbital area of the eye is not a recommended method for eliciting a response from a painful stimulus in an unresponsive patient due to the potential for injury to the eye.
B. Press down on the trapezius muscle.
Pressing down on the trapezius muscle is an acceptable method for eliciting a response from a painful stimulus in an unresponsive patient. This technique is less invasive and can be performed safely to assess the patient's level of consciousness or response to pain without causing harm⁸.
C. Use a 25-gauge needle.
Using a 25-gauge needle is not an appropriate method for eliciting a response from a painful stimulus in an unresponsive patient. This could cause unnecessary harm and is not a standard practice in clinical settings.
D. Elicit a reflex with a reflex hammer.
Eliciting a reflex with a reflex hammer is a method used to assess reflexes, not to elicit a response from a painful stimulus in an unresponsive patient. This tool is used to test neurological function and reflex integrity, not to assess pain response.

A nurse is providing discharge teaching to a client who has pulmonary tuberculosis. Which of the following findings should the nurse include as an indication that the client is no longer infectious?
A. Mantoux skin test revealing an induration of less than 1 mm.
The Mantoux skin test, also known as the tuberculin skin test, measures the immune response to the tuberculin purified protein derivative (PPD) injected under the skin. An induration of less than 1 mm is not necessarily an indication of non-infectiousness; it may indicate a lack of infection or an inadequate immune response. This test does not reflect the current infectious status as it measures a delayed hypersensitivity reaction and can remain positive for life once someone has been exposed to TB or has received the BCG vaccine.
B. Negative sputum cultures for acid-fast bacillus.
Negative sputum cultures for acid-fast bacillus are a strong indication that the client is no longer infectious. Pulmonary tuberculosis is diagnosed and monitored through sputum cultures to detect the presence of Mycobacterium tuberculosis. A series of negative cultures typically indicates that the client is not excreting the bacteria and is, therefore, not contagious.
C. The client is no longer coughing up blood-tinged sputum.
While the cessation of coughing up blood-tinged sputum is a positive sign of clinical improvement, it does not conclusively indicate that the client is no longer infectious. The absence of blood in the sputum may simply mean that the damage to lung tissues is healing, but the client could still be harboring and potentially spreading TB bacteria.
D. Positive Quantiferon-TB Gold test (negative).
The Quantiferon-TB Gold test is a blood test that measures the immune system's response to TB bacteria. A positive result indicates TB infection, but it does not distinguish between latent infection and active disease, nor does it provide information on infectiousness. The parenthetical "negative" is confusing and should be clarified in the context of the test results.
