1. While percussing over the liver of a patient, the nurse notices a dull sound. What should the nurse do?

Correct answer: A

Rationale: When percussing over relatively dense organs, such as the liver or spleen, a dull sound is a normal finding due to the organ's density. This occurs because the sound waves produced by tapping on the organ travel through the dense tissue, resulting in a dull sound. Therefore, the correct action for the nurse in this scenario is to consider a dull sound over the liver as a normal finding. Palpating for an underlying mass (Choice B) is not indicated based on the percussion finding alone. Repositioning the hands and repeating the percussion (Choice C) may not change the dull sound over the liver. Referring the patient for additional treatment (Choice D) without understanding the normal percussion findings over the liver would be premature. Thus, the most appropriate action is to interpret the dull sound as a normal finding.

2. An adult's blood pressure reads 40/20. You place the patient in a Trendelenberg position before rechecking the blood pressure. What actions will you take to position the patient correctly?

Correct answer: A

Rationale: In a Trendelenberg position, used for low blood pressure, the correct action is to lower the head of the bed and raise the foot of the bed. This positioning facilitates the return of blood to the heart and helps increase blood pressure. Option B, raising the head of the bed to 60 to 75 degrees, is incorrect as it is not the Trendelenberg position. Option C, raising the head of the bed to 75 to 90 degrees, is incorrect as it does not align with the Trendelenberg position. Option D, raising the siderails and placing the bed in the high position, is incorrect as it does not address the specific positioning required for the Trendelenberg position.

3. Which type of shock is related to low blood volume?

Correct answer: D

Rationale: Hemorrhagic shock, also known as hypovolemic shock, is directly related to low blood volume due to significant blood loss. In hemorrhagic shock, the body's circulating blood volume is reduced, leading to inadequate perfusion of tissues and organs. Psychogenic shock is caused by emotional distress, not blood volume changes. Cardiogenic shock results from heart failure, not low blood volume. Anaphylactic shock is due to a severe allergic reaction, not a reduction in blood volume.

4. When assessing a patient's pulse, which of the following characteristics would the nurse also notice?

Correct answer: A

Rationale: When assessing a patient's pulse, the nurse should observe characteristics such as rate, rhythm, and force. Force refers to the strength or amplitude of the pulse, which provides important information about cardiac output. Pallor is the paleness of the skin and is not directly related to pulse assessment. Capillary refill time is used to assess peripheral perfusion and is not specifically part of pulse assessment. Timing in the cardiac cycle is a broader concept and not a characteristic directly assessed during a pulse examination. Therefore, choice A, 'Force,' is the correct answer as it aligns with the standard parameters evaluated during pulse assessment.

5. During the general survey, what action is a component of the assessment?

Correct answer: A

Rationale: During the general survey, the nurse assesses the patient's overall appearance, body structure, mobility, and behavior, which includes observing body stature and nutritional status. Interpreting subjective information reported by the patient is part of the subjective data collection process and not the general survey. Measuring vital signs like temperature, pulse, respirations, and blood pressure is part of a focused physical examination, not the general survey. Additionally, observing specific body systems while performing a physical assessment is more specific and focused than the general survey.
